Key

Solid

Solid molecules are tightly packed and have the least amount of energy.

Facts: Solids have definite shape, volume, and density.

Solid

Melting

Adding the amount of energy

Heating up

Liquid

Liquid molecules are loosely packed but have medium amounts of energy.

Facts: Liquids don't have definite shape but have definite volume and density.

Liquid

Evaporating

Adding the amount of energy

Heating up

Gas

Gas molecules spread out to fill the entire space and move freely. And have lots of energy. Facts: Gasses

don't have definite shape, volume or density.

Gas to Liquid

Condensation

Decreasing the amount of energy

Cooling

Liquid

Now the Gas is a Liquid

Liquid to Solid

Freezing

Decreasing amount of energy

Cooling

Solid

Liquid is now a solid

Extras

Gas to Plasma

Ionization

Adding the amount of energy

Heating up

Plasma

Plasma molecules have extremely high level of energy and are electrically charged.

Fact: Plasma don't have any definite shape, volume or density. Plasma is made 99% of the universe. But on Earth Plasma is rare .
