Answer 1

No composition does not change with change in state transition

Explanation:

Matter often changes its state by heating or cooling but that change is physical.

A physical change is the one which does not involve the formation or breakage of bonds. Such as formation of ice from water or formation of water vapors from water.

When water vapors are formed, they have changed the state but the composition is still the same e.g. we still have two hydrogen and one oxygen atom combines as the base molecule.
