Auto Principle: Answer Any Five Questions. Q1a. Define Explain the following heat related terms: 1. Sensible Heat 11. Latent Heat 111. Latent Heat of fusion IV. Latent Heat of Vaporization

To calculate the quantity of heat required to melt the ice, we use the formula for latent heat of fusion, as the ice is already at its melting point ($0^\circ\text{C}$).

Given values:
Mass of ice ($m$) = $5 \text{ kg}$
Latent heat of fusion of water ($L_f$) = $334 \text{ kJ/kg}$
