Two substances, A and B, which are of equal mass but at different temperatures, come into thermal contact. The specific heat capacity of substance B is four times larger than the specific heat capacity of substance A. Which statement is true of the temperature of the two substances when they reach thermal equilibrium? (Assume no heat loss other than the thermal transfer between the substances.)

Question

Two substances, A and B, which are of equal mass but at different temperatures, come into thermal contact. The specific heat capacity of substance B is four times larger than the specific heat capacity of substance A.

Which statement is true of the temperature of the two substances when they reach thermal equilibrium? (Assume no heat loss other than the thermal transfer between the substances.)

a. The final temperature of both substances will be closer to the initial temperature of substance B than the initial temperature of substance A.

b. The final temperature of both substances will be closer to the initial temperature of substance A than the initial temperature of substance B.

c. The final temperature of both substances will be exactly midway between the initial temperatures of substance A and substance B.

d. The final temperature of substance A will be greater than the final temperature of substance B.
