...shame you don't know how to read your text book. Or use the correct tense.
Changes of state of matter are physical processes, the molecule remain unchanged.
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
This is called a change in phase or a phase transition. It occurs when a substance transitions from one of the states of matter (solid, liquid, gas) to another due to changes in temperature or pressure.
It is when a substance changes it's form of matter, such as ice ( a solid) melting into water ( a liquid).
nothings its a dumb question
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
water!
Molecules can change states of matter through the processes of melting, freezing, vaporization, condensation, and sublimation. These changes in state occur when the temperature or pressure of the substance is altered, causing the molecules to rearrange in a way that transitions the substance from one state to another.

The "blank form" could be "state".
This is called a change in phase or a phase transition. It occurs when a substance transitions from one of the states of matter (solid, liquid, gas) to another due to changes in temperature or pressure.
During phase changes the temperature of a substance does not change.
Change of state of a substance is a physical property!
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
Physical changes.
