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 5.37 kg; sample B has a mass of 1.64
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 AT, = 4.10 °C.
