Temperature of a 0.50 kg sample as a function of heat added.
Temperature of a 0.50 kg sample as a function of heat added.
A \(0.50 \text{ kg}\) sample of an unknown pure substance, initially in the solid phase at \(20^\circ\text{C}\), is heated at a constant rate in an insulated container. The graph shows the temperature \(T\) of the sample as a function of the heat added \(Q\). Based on the graph, what is the latent heat of fusion of the substance?
