A 2-kg block of solid ice (at 0ºC) is to be completely melted. If the heat of fusion of water is $3.34 \times 10 ^ { 5 }$ J/kg, what amount of heat is required?

Question

Quizplus · Accepted Answer

The heat required to melt the ice is calculated using the formula: $ Q = m \times L_f $, where $ m $ is the mass and $ L_f $ is the heat of fusion. For 2 kg of ice, $ Q = 2 \, \text{kg} \times 3.34 \times 10^5 \, \text{J/kg} = 668,000 \, \text{J} = 668 \, \text{kJ} $.
