Question

The amount of heat energy required to melt 1 kg of a substance at its melting point, without any rise in temperature is known as:

विकल्प

• specific latent heat of fusion

• latent heat of fusion

• heat capacity

• specific heat capacity

Answer 1

Specific latent heat of fusion

Explanation:

Specific latent heat of fusion is the heat needed to melt a unit mass at its melting point without a temperature rise. Latent heat of fusion is for a given mass, while heat capacity and specific heat capacity describe heating that changes temperature.
