A body cools in a cold surrounding obeying Newton's law of cooling. It is found that from t = 0 to t = t1 A cylindrical rod of heat capacity 120J/K in a room temperature 27C is heated internally by heater of power 250W from t = t1 will it loose one fourth the total heat? it loses half the total heat. In what time
