If mass-energy equivalence is taken into account, when water is cooled

1.	If mass-energy equivalence is taken into account, when water is cooled to form ice, the mass of water should(a) Increase(b) remains unchanged(c) decrease(d) first increase then decrease
Answer» Correct Option (a) Increase Explanation : According to the mass-energy equivalence, mass and energy remain conserved. So, when water is cooled to form ice, water loses its energy so, change in energy increases the mass of water.
