Question

Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at 100º 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
(1) 50° C
(2) more than 50° C
(3) less than 50° C but greater than 0° C
(4) 0° C

Answer 1

Answer:

Since, heat capacity of material increases with increase in temperature so, body at 100°C has more heat capacity than body at 0°C. Hence, final common temperature of the system will be closer to 100°C.

Tc > 50°C

so option (b) more than 50°C is correct answer of your question.
