Q. Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at 100 °C, while the other one is at 0 °C. If the two bodies are brought into contact, then, assuming no heat loss, 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
Explanation
[Solution] The hotter body has the larger heat capacity, so it cools less than the colder body warms; the final temperature is above 50 °C. Answer (2).
