This is a problem I came across: Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is at 100 ºC, while the other one is at 0 ºC. If the two bodies are brought into contact, then assuming no heat loss, the final common temperature is (A) 50 degree Celsius (B) less than 50 degrees but greater than 0 degree Celsius (C) more than 50 degrees (D) none
The answer is (C) more than 50 degrees Celsius. I do not understand why. No relation of temperature dependence with heat capacity is given, whether it varies linearly or in another power of temperature,etc.
