Question

31. Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these at 100 °C, while the other one is at 0 °C. If the two bodies are brought into contact, then, assuming no heat lose, the final common temperature is
(a) 50 °C
(b) more than 50 °C
(c) less than 50 °C but greater than 0 °C
(d)0°C
​

Answer 1

Answer:

b)

Explanation:

Heat capacity rise with temperature, so less temperature will drop in higher temperature body when an equal amount of heat is transferred from lower temperature body which rises more in temperature. Therefore, the final temperature will be more than 50°C.
