If mass-energy equivalence is taken into account , when water is cooled to form ice, the mass of water should :-(Note: The mass energy of an object is the energy equivalent of its mass , as given by `E= mc^(2)`, where m= mass of object & c = speed of light)

A

increase

B

remain unchanged

C

decrease

D

first increase then decrease

Text Solution

Verified by Experts

The correct Answer is:
C
When water is cooled to form ice , the energy is released as heat so mass of water decreases.
