Object A, with Heat Capacity C_A and Initially at Temperature

question 82

Multiple Choice

Object A, with heat capacity C_A and initially at temperature T_A, is placed in thermal contact with object B, with heat capacity C_B and initially at temperature T_B.The combination is thermally isolated.If the heat capacities are independent of the temperature and no phase changes occur, the final temperature of both objects is:

• A)(C_AT_A - C_BT_B)/(C_A + C_B)
• B)(C_AT_A + C_BT_B)/(C_A + C_B)
• C)(C_AT_A - C_BT_B)/(C_A - C_B)
