1. Continuum Assumption is the value of properties, like density which does not depend on the size or the shape of what is being measured. It vary continuously through space. Continuum assumption also discusses that fluids can be treated to be something continuous through space

2. Gases and liquids are categorized as fluids due to their ability to continuously deform. As discussed on the video, fluid is something that can continuously deform, in which gases and liquids have the ability to do so. Their molecules, as well are both apart and isn't compact unlike that of the solids, making them able to move.

3. Elastic collision does not lose it's kinetic energy through the process of collision. On the other hand, inelastic collision turns a part of the kinetic energy to be charged in to some form of energy on the process of collision.

4. Two other equations of state are Virial Equation of state in which the temperature-dependent constants for each gas are known as the virial coefficients . The van der Waals equation is an equation of state that corrects for two properties of real gases: the excluded volume of gas particles and attractive forces between gas molecules

5. Newton's law of viscosity states that a shear stress is being directly proportional to velocity gradient. The shear stress between the two adjacent layers of fluid is directly proportional to the negative value of the velocity gradient between the same two adjacent fluid layers.

6. Tensor as explained on the video is related to scalar and vector but, tensor includes 1 value and 2 different directions. Whereas, on the other hand, vector has 1 value or magnitude and also 1 direction.

7. The difference between pressure and sheer stress is that, pressure acts normal towards the surface, it acts inward the surface while shear stress, acts parallel to the surface. Shear stress in fluid is due to the friction from fluid viscosity.

8. Non newtonian : https://www.google.com/url?sa=i&url=https%3A%2F%2Fphysicsworld.com%2Fa%2Fthe-physics-of-blood-spatter%2F&psig=AOvVaw0STlU8m-Fvnhp5Soo0OnRF&ust=1598768858469000&source=images&cd=vfe&ved=0CAIQjRxqFwoTCIiE9aHkv-sCFQAAAAAdAAAAABAD

1. properties like density can be considered with this that vary continuously through space.
2. Gases categorize as fluid because of it move continuously, has large molecular space and small intemolecular forces. While liquid is also the same as gas that's why they called as fluid.
3. Inelastic collision is one of which part of the kinetic energy changed to some other form in collision while elastic defiend as the total kinetic energy and total momentum before and after are the same.
4. Kamerlingh Ones Equation of state, expresses PV as power series of pressure,
Berthelot Equation,high pressure form. Useful in calculating molecular weight.

The continuum assumption erases the molecular discontinuities by averaging the microscopic quantities on a small sampling volume. All macroscopic quantities of interest in classic fluid mechanics (density ρ, velocity u, pressure p, temperature T, etc.) are assumed to vary continuously from point to point within the flow.

1.) continuum assumption - density, pressure, temperature are assumed to be changing from point to point within a flow

2,) they can be deformed by shear force

3.) Elastic collision is a collision where there’s no loss in kinetic energy, while inelastic collision occurs when the kinetic energy is not conserved. Furthermore there’s 2 types of inelastic collisions: perfectly inelastic and partially inelastic. The former involves colliding objects that stick together after the collision, while the latter involves objects in collision to separate afterwards.
4.) a.) Cubic equation of state - express the pressure as a cubic function of the molar volume, and their origin stems from the van der Waals equation, which was the first cubic equation of state to represent qualitatively both vapour and liquid phases.

b.) virial equation of state is used to describe the behavior of diluted gases. It is usually written as an expansion of the compressibility factor, , in terms of either the density or the pressure.

1. Continnum assumption recognizes a scale as continuous if it is shown on a larger box but as we zoom in and look at it on a
microscopic scale we see that the number of molecules actually differ at different points of the scale. Meaning if we were
to take a measurement on one part, the other would drastically be different.
2. They can both be deformed by shear force.
3. In elastic collision the energy and momentum remains the same before and after the collision meanwhile on inelastic the energy can be converted to another form.
5. Newton's Law of Viscosity. The shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers.

1. When applicable, the continuum assumption is very convenient since it erases the molecular discontinuities by averaging the microscopic quantities on a small sampling volume. All macroscopic quantities of interest in classic fluid mechanics (density ρ, velocity u, pressure p, temperature T, etc.) are assumed to vary continuously from point to point within the flow.

For example, if we consider an air flow in a duct, for which the macroscopic velocity varies from 0 to 1 m/s and is parallel to the axis of the duct, the velocity of a molecule is on the order of 1 km/s and may take any direction. Similar considerations also concern the other mechanical and thermodynamic quantities.

2. Fluids are a phase of matter and include liquids, gases and plasmas. They are substances with zero shear modulus, or, in simpler terms, substances which cannot resist any shear force applied to them.

3. Elastic collision is a collision where there’s no loss in kinetic energy, while inelastic collision occurs when the kinetic energy is not conserved. Furthermore there’s 2 types of inelastic collisions: perfectly inelastic and partially inelastic. The former involves colliding objects that stick together after the collision, while the latter involves objects in collision to separate afterwards.

5.Newton's law of viscosity defines the relationship between the shear stress and shear rate of a fluid subjected to a mechanical stress. The ratio of shear stress to shear rate is a constant, for a given temperature and pressure, and is defined as the viscosity or coefficient of viscosity.

6. Tensors are simply mathematical objects that can be used to describe physical properties, just like scalars and vectors. In fact tensors are merely a generalisation of scalars and vectors; a scalar is a zero rank tensor, and a vector is a first rank tensor.

7, Pressure is an example of a normal stress, and acts inward, toward the surface, and perpendicular to the surface. A shear stress is an example of a tangential stress, i.e. it acts along the surface, parallel to the surface.

An elastic collision is a collision in which the colliding objects bounce back after the collision without the generation of any heat or the deformation of any of the objects. Total kinetic energy and the total momentum before and after the collision are the same. On the other hand, in an inelastic collision, the shapes of the colliding objects become distorted and/or heat is generated as a consequence of the collision and some of the energy gets converted into other forms of energy such as sound energy or thermal energy.

1. Continuum Consumption - studies the behavior of materials by ignoring its particulate nature.
2. Liquids and gases are are categorize as fluids because they can flow or move.
3. Inelastic collision - there is a loss of KE. Momentum is conserved in the system but the KE is not because it hab been transferred to something else.
Elastic collision - there is no loss in KE in the system. Both momentum and KE are conserved.
4. Peng - Robinson Eq. - used to calculate the vol. of 100% methane gas as a funtion of pressure and temp.

1) Discuss the continuum assumption.
Fluids can be treated as continuous, even though, on a microscopic scale, they are composed of molecules - as said on the video, the individual variations doesn't matter because the volume contains enough molecules

2) What categorizes gases and liquids as fluids?
Gases and liquids are fluids because they can be made to flow or move.

3) Differentiate Inelastic and Elastic Collision.
An elastic collision is defined as one in which there is no loss of kinetic energy in the collision while an inelastic collision is one in which part of the kinetic energy is changed to some other form of energy in the collision.

4) Search for two other equations of states aside from ideal gas law. What are the features of these equations of state?
(1) Kamerlingh-Onnes EQ
(2) Van der Waals EQ

5) What is Newton's Law of Viscosity?
Newton’s viscosity law’s states that, the shear stress between adjacent fluid layers is proportional to the velocity gradients between the two layers.

The ratio of shear stress to shear rate is a constant, for a given temperature and pressure, and is defined as the viscosity or coefficient of viscosity.

6) What is a tensor? vector?
Tensors are simply mathematical objects that can be used to describe physical properties, just like scalars and vectors. In fact tensors are merely a generalisation of scalars and vectors; a scalar is a zero rank tensor, and a vector is a first rank tensor.

7) How is shear stress different from pressure?
Pressure and shear stress have one major difference—that is, their direction. Pressure always acts normal to the surface whereas shear stress always acts parallel to the surface. For both case, stress are obtained by dividing force with area.

8) Can you post examples of Newtonian and Non-Newtonian fluids? (you can use photos from online sources)

Water, air, alcohol, glycerol, and thin motor oil are all examples of Newtonian fluids over the range of shear stresses and shear rates encountered in everyday life.

Ketchup, for example, becomes runnier when shaken and is thus a non-Newtonian fluid. Many salt solutions and molten polymers are non-Newtonian fluids, as are many commonly found substances such as custard, honey, toothpaste, starch suspensions, corn starch, paint, blood, melted butter, and shampoo.

b. Virial Equation of State - The parameters in the equation (B,C,D = c_i) are called "virial coefficients". If c_i=0 for i>0, the virial equation reduces to the ideal gas equation. Just as with the ideal gas equation, the temperatures and pressures used must be absolute.

1. The continuum assumption considers fluids to be continuous, rather than discrete. Consequently, properties such as density, pressure, temperature, and velocity are taken to be well-defined at infinitesimally small points, and are assumed to vary continuously from one point to another. The fact that the fluid is made up of discrete molecules is ignored.

2. Gases and liquids categorizes as fluids because they can flow and move. They also yield to shearing force.

3. Elastic collision is the one with no loss of kinetic energy in the collision while inelastic collision the kinetic energy changed to another form in the collision.

4. Dalton's law of partial pressures states that the pressure of a mixture of gases is equal to the sum of the pressures of all of the constituent gases alone.

The van der Waals equation is an equation of state that corrects for two properties of real gases: the excluded volume of gas particles and attractive forces between gas molecules.

1) Discuss the continuum assumption.

// Continuum Assumption //

On a smaller scale, the measurement of molecules is constantly changing therefore more fluctuations on its data but assuming the volume contains enough molecules helps on the treating fluid as continuous
Value of property doesn’t depend on the space it occupies

2) What categorizes gases and liquids as fluids?

// Fluids //

Generally, gases and liquids are categorized as fluids because of its properties regarding motion. Both the states of matter have the ability to flow or move in a given space (pipes and such).

3) Differentiate Inelastic and Elastic Collision.

// Inelastic Collision //

A type of collision where the object involved in it collide on a certain point and would then be considered as one mass. Here, the total momentum is conserved but the kinetic energy isn’t (the energy converts into something else).

// Elastic Collision //

A type of collision where the objects involved remain separate after the collision. The total kinetic energy and elastic energy are conserved (no energy loss).

4) Search for two other equations of states aside from ideal gas law. What are the features of these equations of state?

// Van Der Waal’s Equation (1873) //

Accounts for the non ideal nature of gas (improved ideal gas law)
Attraction between molecules and the volume taken up by the particle (known as true volume) is taken into account and considered (constants a and b are added as correction to the ideal gas)

// Redlich-Kwong equation of state (1949) //

More accurate than ideal gas and Vanderbilts wall’s equation at critical temperature
It still uses the constants a and b derived from Vander Waal’s Equation but the attraction of molecules (at parameter a) were needed to be made as a function of temperature to be quantitatively accurate

5) What is Newton's Law of Viscosity?

// Newton's Law of Viscosity //

" Newton's law of viscosity states that shear stress is directly proportional to velocity gradient. The shear stress between the two adjacent layers of fluid is directly proportional to the negative value of the velocity gradient between the same two adjacent fluid layers "
The law says that no matter stress you put on a Newtonian fluid (like air and water), its viscosity will remain the same is independent with stress. Non-Newtonian fluids do not apply to the law because its viscosity can change under stress (quicksand, honey, cornstarch w/ little water etc.)
