In two experiments with a continuous flow calorimeter to determine the specific heat capacity of a liquid, an input power of 60W produced a temperature rise of 10K in the liquid. When the power was doubled, the same temperature was achieved by making the rate of flow of liquid three times faster. The power lost to the surroundings in each case was-A)20W B)40W C)30W D)120W
