A metallic ball and highly stretched spring are made of the same material and have the same mass. They are heated so that they melt. The latent heat required

A

are the same for both

B

is greater for the ball

C

is greater for the spring

D

for the two may or may not be the same depending upon the metal

Text Solution

Verified by Experts

The correct Answer is:
