Question

Identify the correct value for the latent heat of fusion of ice.

• A. 150 kJ/kg
• B. 220 kJ/kg
• C. 336 kJ/kg
• D. 580 kJ/kg

Answer 1

The correct option is C 336 kJ/kg

Water and ice have the same latent heat of fusion or melting. It is defined as the amount of heat liberated (or supplied) when a kilogram of ice (or water) melts (or freezes) at $0{}^{\circ }\text{C}$. It is equal to $336000{\text{J kg}}^{-1}$ or $336{\text{kJ kg}}^{-1}$.
