The amount of heat necessary to change 1 kg of a solid into a liquid at the same temperature is called the Group of answer choices

Latent heat of fusion

Explanation:

The amount of heat required to change the state of a unit mass (say 1kg) of a substance is called latent heat. This change typically occurs without a significant change in temperature. The latent heat occurs as a result of the work required to break the forces that hold atoms or molecules in a given matter (solid, liquid or gas). Now, since the transformation is from solid into liquid, the amount of heat required to do this is called the latent heat of fusion. This transformation takes place at the melting point of the solid.
