easy

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

Are the same for both

Is greater for the ball

Is greater for the spring

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

(AIIMS-2002)

Solution

(a)Latent heat is independent of configuration. Ordered energy spent in stretching the spring will not contribute to heat which is disordered kinetic energy of molecules of substance.
