False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.
This is called a change in the physical state of the substance. For example formation of ice from water is a change in the physical state of water.
A change that does not make a substance into a new substance is called a physical change. In physical changes, the physical properties of the substance may change, such as shape, size, or state (solid, liquid, gas), but the chemical composition remains the same.
The chemical composition of the substance does not change when it changes its state of matter. The arrangement of atoms and molecules may vary, but the elements present in the substance remain the same.
A physical change.Changes between Solid, Liquid, and Gas.
change of state
change is complete
False. The temperature of a substance remains constant during a change in state until all of the substance has completed the phase change.

One possibility is a change in state.
change of state
physical change
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
No. Freezing represents a physical change from the liquid to the solid state. The composition of the substance does not change.
One possibility is a change in state.
Change of state of a substance is a physical property!
Change the temperature or pressure or both, to change a substance from one state to another. (such as gas to liquid)
