Answer:
Look down to the explanation
Explanation:
Because matter is extrinsic property ( meaning it could be changed based on the enviornment), things like pressure and temperature can affect the state and form of matter. "When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation)." So if the temperature is increased, it is the cause of thermal/heat energy, and this is what makes solids into liquids, liquids to gasses, and gasses to plasma (including other additional states.
Anyways, I hope this helps, and sorry it's long!
