Solid <-> liquid <-> 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.
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.
change of state
One possibility is a change in 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!
No. Roughly speaking, "specific gravity" is equivalent to density, i.e., mass divided by volume. If a substance changes its state, its volume will change, but its mass won't change - therefore, the density - the result of the division - will also change.
