If mass-energy equivalence is taken into account, when water is cooled to from ice, the mass of water should

A

Increase

B

Remain unchanged

C

Decrease

D

First increase then decrease

Text Solution

Verified by Experts

The correct Answer is:
B
When water is cooled at `0^(@)C` to from ice then `80 "calorie"//gm` (latent heat) energy is released. Beacuse potential energy of the molecules decreases. Mass will remain constant in the process of freezing of water.
