The amount of energy required to change a kilogram of ice in water without a change in temperature is
Answer Details
The amount of energy required to change a kilogram of ice into water without a change in temperature is the specific latent heat of fusion of ice.
When a substance changes from one phase to another, it requires energy to break the bonds between the molecules in the original phase and form new bonds in the new phase. In the case of ice changing into water, the bonds between the molecules in the solid ice must be broken in order to form liquid water.
The specific latent heat of fusion of ice is the amount of energy required to change a kilogram of ice into water without a change in temperature. This value is specific to the substance and phase transition, and represents the amount of energy required to break the bonds between the molecules in the solid phase and form a liquid.
Therefore, to change a kilogram of ice into water without a change in temperature, you would need to add energy equal to the specific latent heat of fusion of ice.
Option (D) specific latent heat of fusion of ice is the correct answer.
