Question
Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is held at a temperature of 100 while the other one is kept at 0. If the two are brought into contact, then, assuming no heat loss to the environment, the final temperature that they will reach is :

Solution
The correct option is A More than 50
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. hence the final temperature will be higher than 50.
