Question

Answer 1

1.    The change is reversible. A substance can revert back to its original state by physical means.

2.    No new chemical substance is formed. The chemical identity of the substance remains the same in the different states. Ice,water and water vapour are chemically H2O although they are present as solid, liquid and gaseous states respectively.

3.    There is no change in the chemical properties of the substance.
