Vedclass · Answer

(A) Latent heat is a property of the material that depends on the mass of the substance undergoing a phase change. It is defined as $Q = mL$,where $m$ is the mass and $L$ is the specific latent heat of fusion. Since both the metallic ball and the spring are made of the same material,their specific latent heat $L$ is identical. Given that their masses $m$ are also the same,the total latent heat required $Q$ must be the same for both. The energy spent in stretching the spring is stored as elastic potential energy,which is an ordered form of energy. Latent heat,however,relates to the energy required to overcome intermolecular forces during a phase transition,which is independent of the initial configuration or the internal elastic energy of the object.

$A$ metallic ball and a 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:
