Physical Properties:  They are easy to compress.  They expand to fill their containers.  They occupy far more space than the liquids or solids from which they form.
Inter molecular Forces:  The average kinetic energy of the particles in a gas is great enough to overcome the forces of attraction between them. The molecules of a gas move apart when they collide.
Common Examples:  Helium, Hydrogen, Nitrogen, Oxygen, and Carbon Dioxide.

Physical Properties:  Odor, Color, Volume, Density, Melting Point, Boiling Point, Heat Capacity,  Physical Form, Shape at Room Temp, and Hardness.
Inter Molecular Forces: It keeps the same shape. They're almost not compressible.  The particles don't flow.  The diffusion of solids happen very slowly.
Common Examples:  Wood, Bricks, Steel, Bricks, Metal, and Glass.

Physical Properties:  Plasma carries electrical currents.  They also generate magnetic fields.  Plasma is a conductive charged particle.
Inter Molecular Forces:  It's a collection of electrons and ions.  Other then this example, there are really none.
Common Examples: Lightning, Stars, Auroras, and Solar Wind. ]]> 2017-03-14 15:46:14 UTC https://padlet.com/20cchristians/u6bw3du0xzzb/wish/160021712 20cchristians https://padlet.com/20cchristians/u6bw3du0xzzb/wish/160705899 Definition:   A substance that flows freely but is of constant volume, having a consistency like that of water or oil.
Physical Properties:  They're almost not compressible.  They have fixed volume but no fixed shape or definite shape.  Boiling point is above room temp.
Inter Molecular Forces:  Hydrogen bonds are common.  Also dipole-dipole, dipole-induced dipole, and induced dipole-induced dipole.
Common Examples:  Water, Juice, Ethanol, Milk, and Alcohol.

Each element is distinguished by its atomic number, the number of protons in the nuclei of its atoms.
Compounds:  A thing that is composed of two or more separate elements.
Pure Substances:  Substances that are made of only one type of atom or only one type of molecule.
Mixtures:   Substance made by mixing other substances together.]]> 2017-03-17 13:30:01 UTC https://padlet.com/20cchristians/u6bw3du0xzzb/wish/160787529 20cchristians https://padlet.com/20cchristians/u6bw3du0xzzb/wish/160788675 An atom is the basic unit that makes up everything.  It's structure consists of protons, neutrons, and electrons.

Examples:  Color, Smell, Freezing Point, Boiling Point, and Melting Point.

Examples: Toxicity, Flammability, and Combustion.

Classification:  Mixtures can be either homogeneous or heterogeneous. A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties. A heterogeneous mixture is a type of mixture in which the components can be seen, as there are two or more phases present.
Heterogeneous:  Salt, Pepper, Chocolate Chip Cookies, Twix.
Homogeneous:  Water, Alcohol, Coffee, Mouth Wash,  Laundry  Detergent.
Separation: Homogeneous mixtures can be separated by boiling and distillation. Heterogeneous mixtures can be separated through chromatography and/or filtration.
