JEE MAIN - Physics (2002 - No. 34)
If mass-energy equivalence is taken into account, when water is cooled to form ice, the mass of water should
increase
remain unchanged
decrease
first increase then decrease
Explanation
When water is cooled to form ice, energy is released from water in the form of heat. As energy is equivalent to mass therefore when water is cooled to ice, its mass decreases.
