A solid of mass 2.0 kg receives heat at a rate of 1.0 × 10^5 J per minute. Its temperature T (in K) during the first 45 minutes is shown in the graph on the opposite page.

State, giving your reasoning, whether the specific heat capacity of the liquid is greater or smaller than that for the solid state.

The mark scheme is shown once you've answered.
