Factors such as the amount of a substance, its chemical composition, and the presence of impurities will not change its state of matter. For instance, heating or cooling a substance can change its state (e.g., solid to liquid), but simply having more or less of the same substance at the same temperature and pressure will not alter its state. Additionally, the state of matter remains unchanged as long as the temperature and pressure conditions stay constant.
a change in size, shape or the state of matter is a physical change. True for A+.
Because melting is a change of state: from solid to liquid.
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!
Because it a change of state of matter in this case of the the matter in question is gas.
A solid is a state of matter that does not change in volume because the particles are closely packed together and have fixed positions.
The state of matter remain unchanged.
no physical change does not change matter
Change of state.

It can.
Because melting is a change of state: from solid to liquid.
A change in the state of matter occurs when heat energy is added or removed.
phase change.
