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

Options

A. `50^(@)C`
B. more than `50^(@)C`
C. less than `50^(@)C` but greater than `0^(@)C`
D. `0^(@)C`

Answer

B

Explanation

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 tempeature of the system will be closer to `100^(@)C`.
