Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at 100  o C , while the other one is at 0  o C . If the two bodies are brought into contact, then assuming no heat loss, the final common temperature is

Step-by-step solution

Loss of heat by the hot body = gain of heat by the cold body. Since, the heat capacity increases with temperature, the hotter body will lose more energy when its temperature falls down from 100   o C to 50   o C compared to the energy required by the cold body to raise its temperature from 0   o C to 50   o C . Thus, the temperature will be more than 50   o C .
