Liquid is filled in a vessel which is kept in a room with temperature 20 C. When the temperature of the liquid is 80 C, then it looses heat at the rate of 60 cal/s What will be the rate of loss of heat when the temperature of the liquid is 40 C

180 cal/s

40 cal/s

30 cal/s

20 cal/s

Rate of loss of heat $\propto$ difference in temperature of body and the surrounding

$\implies \dfrac{H_2}{H_1}=\dfrac{40-20}{80-20}=\dfrac{1}{3}$

$\implies H_2=20cal/s$
