Question

Two solid objects of the same mass are supplied with heat at the same rate $Δ Q /Δ t$ . The temperature of the first object with latent heat $L_{1}$ and specific heat capacity $c_{1}$ changes according to graph 1 on the diagram. The temperature of the second object with latent heat $L_{2}$ and specific heat capacity $c_{2}$ changes according to graph 2 on the diagram. Based on what is shown on the graph, the latent heats $L_{1}$ and $L_{2}$ and the specific heat capacities $c_{1}$ and $c_{2}$ in solid state obey which of the following relationships:

TestHub · Accepted Answer

At equal mass and input power, the melting plateau duration is proportional to latent heat.
$L \propto Δ t_{plateau}$
Curve 2 has the longer plateau.
$L_{1} < L_{2}$
Before melting, the slope is inversely proportional to specific heat.
$\frac{d T}{d t} = \frac{P}{m c}$
Curve 1 is steeper.
$c_{1} < c_{2}$
