In two experiments with a countinous flow calorimeter to determine the specific heat capacity of a liquid,an input power of 16 W produced a rise 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. Find the power lost (in W) to the surrounding in each case.

Answer

8

Explanation

Let power lost to surrounding be P
`rArr16-P=((dm)/(dt))s(10)and,32-P=3((dm)/(dt))s(10)rArr(32-P)/(16-P)=3rArrP=8W`
