Problem
Objects A and B that are initially separated from each other and well isolated from their surroundings are then brought into thermal contact. Initially T_A = 0°C and T_B = 100°C. The specific heat of A is less than the specific heat of B. After some time, the system comes to an equilibrium state. The final temperatures are:
(a) T_A = T_B > 50°C
(b) T_A > T_B > 50°C
(c) T_A = T_B < 50°C
(d) T_B > T_A > 50°C
(e) T_A = T_B = 50°C
