I believe "heat"
To change from one state of matter to another state of matter heat is added or taken away.
I think that makes sense!
Mass
heat is added
move faster and break free from other particles, entering the gas state.
Changes in the state of matter occur when the amount of heat energy is changed in a substance. When it is removed, gas condenses and liquid freezes. When it is added, solids melt and liquids boil.
Generally the temperature of the material. Pressure can change the temperatures at which transformations occur.
The change in which no new kinds of matter are formed but the size, shape or state of the matter may change is known as a physical change.
heat is added
A change in the state of matter occurs when heat energy is added or removed.
For example, the change in the state of matter.
mass cannot change quanity if it is not added or removed
move faster and break free from other particles, entering the gas state.
move faster and break free from other particles, entering the gas state.
Energy must be added or taken away.

They do Occur in SOLID,LIQUID and GAS
Matter causes a change in state
The state of matter remain unchanged.
