Question

In two experiments with a continuous flow calorimeter to determine the specific heat capacity of a liquid, an input power of 60 W produced arise of 10 K in the liquid. When the power was doubled, the same temperature rise was achieved by making the rate of flow of liquid three times faster. If power loss in each case is same then find power lost to the surroundings :-

Options:

Answer:

C

Solution:

Let loss be H. Then 60-H=10mc and 120-H=30mc.

Eliminating mc gives H=30 W.
