|
|
Amount of Energy needed for 1Kg of a substance to change state
|
|
|
Either A or B
|
|
|
None of the above

Explanation:
Detailed explanation-1: -This is called as latent heat of fusion. It is defined as the amount of heat energy that is required to change 1 kg of a solid into liquid at atmospheric pressure at its melting point. The latent heat of the ice is 80 Cal/g and 3.34 × 105 J/kg.
Detailed explanation-2: -An input of 334, 000 joules (J) of energy is needed to change 1 kg of ice into 1 kg of water. The same amount of energy needs to be taken out of the liquid to freeze it.
Detailed explanation-3: -Latent heat of fusion of ice=3.36×105 Jkg−1.
