energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.

Nuclear energy is stored in the nucleus of atoms. This energy is released when the nuclei are combined (fusion) or split apart (fission). Nuclear power plants split the nuclei of uranium atoms to produce electricity.

Chemical energy is stored in the bonds of atoms and molecules – it is the energy that holds these particles together. Stored chemical energy is found in food, biomass, petroleum, and natural gas.

Also known as light energy or electromagnetic energy, radiant energy is a type of kinetic energy that travels in waves. Examples include the energy from the sun, x-rays and radio waves.

Electrical energy is the movement of electrons (the tiny particles that make up atoms, along with protons and neutrons). Electrons that move through a wire are called electricity. Lightning is another example of electrical energy.

Thermal energy is created from the vibration of atoms and molecules within substances. The faster they move, the more energy they possess and the hotter they become. Thermal energy is also called heat energy

What is the Law of Consevation of Energy?

# data[].attributes.body
The First Law of Conservation of energy simply states that energy can never be created or destroyed, but it can be transformed from one type to another.

Energy conversion- the transformation (change) of energy from forms provided by nature to forms that can be used by humans.

Kinetic energy is the energy of a moving object. kinetic energy (KE) of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity

EM waves are waves that are created as a result of vibrations between an electric field and a magnetic field. In other words, EM waves are composed of oscillating magnetic and electric fields.

is energy that is stored in an object or substance. potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.

1-Static friction acts on objects when they are resting on a surface.
2-Sliding friction is friction that acts on objects when they are sliding over a surface. Sliding friction is weaker than static friction.
3-Rolling friction is friction that acts on objects when they are rolling over a surface. Rolling friction is much weaker than sliding friction or static friction.
4-Fluid friction is friction that acts on objects that are moving through a fluid.

Introduction:  What do you expect to learn? What is the purpose of this lab?

Freezing time and freezing temperature of different liquids are among the most important physical properties of that liquid. These physical properties may change when other materials are dissolved in or mixed with the liquids. This project will discover this subject using water and sugar that are both safe and available in most households.

Hypothesis:

plain water will freeze the fastest and saltwater the slowest. My reasons for this prediction are based upon the facts that (1) adding sugar or salt to water lowers the freezing point and (2) seawater hardly freezes.

Materials/Resources used for the experiment

5 clear plastic cups

1. Water

2. Sugar

3. Salt

4. Freezer

Procedure:

Clean water – 160 mml

1 table-spoon sugar water – 160 mml

2 tablespoon sugar water – 160 mml

1 tablespoon saltwater – 160 mml

2 tablespoons saltwater – 160 mml

The 1st Step - Pour the 5 different types of water in 5 separated clear plastic cups and put them in a freezer

The 2nd Step - Observe the 5 types of water in the freezer every 30 minutes

Explain your data in words:

All the cups got colder at 4:00 PM, Clear water was frozen on 5:00 Pm. 1Tbs sugar cup frozen at 6:00pm while 2 Tbs sugar cup frozen at 6:30 pm. Moving to salt; 1 tbs salt cup frozen at 10:30 pm.  Clean water took 1 hour and 30 minute’s, 1 tbs of sugar to two hours and 30 minutes 2 Tbs of sugar took 3 hours. While 1 tbs of salt took 7 hours and 2 tbs of salt took 20 hours to frozen

Conclusion:

This experiment shows 2 conclusions confirming the proposed hypothesis. First, the plain water freezes first since it gets to its freezing temperature, while the sugar water and saltwater are still getting colder. And second, it also shows that the freezing point of saltwater is lower than that of sugar water. The second conclusion can explain that we hardly see frozen seawater, while there are many sweet ice stuffs.
