Question
The heat required to melt 1 kg of a substance is called its _____.
- Specific heat capacity
- Specific latent heat of fusion
- Specific latent heat of vaporization
- Heat capacity
Hint:
specific latent heat of fusion
The correct answer is: Specific latent heat of fusion
The amount of energy required to change the state of 1 kg of a material is known as specific latent heat.Hence the amount of heat needed to turn 1 Kg of solid into liquid at atmospheric pressure at its melting point is known as specific latent heat of fusion.
