Q 1 :    

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         [2016]

  • 50°C

     

  • more than 50°C

     

  • less than 50°C but greater than 0°C

     

  • 0°C

     

(2)

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.
