Gas
Acts like gases, but their particles move so fast and collide so hard that they break apart and become electrically charged
Plasma
A solid becomes a liquid
Melting
A liquid becomes a solid
Freezing
A liquid becomes a gas using heat
Vaporization
If vaporization happens so fast that the liquid forms bubbles that rise through the liquid
Boiling
A liquid becomes a gas in between the melting point and the boiling point of the liquid
Evaporation
When vapor particles stick together
Condensation
A solid becomes a gas
Sublimation
A gas becomes a solid
Deposition
The gravatational pull exerted on an object by another very large object, such as the Earth
Weight
The measure of the space something occupies
Volume
A push or pull
Force
