Question

2995.9 kJ of heat is required to convert a 14.6 kg sample of
copper from the solid to liquid phase. What is the heat of
fusion of copper in kJ/kg?

Answer 1

Answer:

205.20 kJ/kg is the heat of fusion of copper in kJ/kg.

Explanation:

Heat of fusion is defined as heat provided to specific mass of solid to change its state from solid to liquid.

Amount of heat required to convert solid copper into liquid = Q = 2995.9 kJ

Mass of copper m = 14.6 kg

Heat of fusion of copper = $\Delta H_{fus}=\frac{Q}{m}$

$=\frac{2995.9 kJ}{14.6 kg}=205.20 kJ/kg$

205.20 kJ/kg is the heat of  fusion of copper in kJ/kg.
