Students have asked these similar questions
Is their final temperature greater than, less than, or equal to 100 degrees Celsius?
A. Since the specific heat of cube A is greater than that of B, more heat is required to raise the temperature of cube A by the same value. Therefore, the final temperature would be lower than 100 degrees Celsius
B. Since both cubes have the same mass, they same internal energy in the equilibrium state. Therefore, the final temperature of both cubes would be equal to average value of the initial temperatures, 100 degrees Celsius.
C. Since the specific heat of cube A is greater than that of B, less heat transfers from B to A than should transfer from A to B to reach the thermal equilibrium. Therefore, the final temperature would be greater than 100 degrees Celsius.
D. We do not have enough information to answer the 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.
