Samples A and B are at different initial temperatures when they are placed in a thermally insulated container and allowed to come to thermal equilibrium. Figure (a) gives their temperatures T versus time t. Sample A has a mass of 5.52 kg; sample B has a mass of 1.32 kg. Figure (b) is a general plot for the material of sample B. It shows the temperature change AT that the material undergoes when energy is transferred to it as heat Q . The change AT is plotted versus the energy Q per unit mass of the material, and the scale of the vertical axis is set by ATs = 3.90 C.
