Question

The water equivalent of a body, whose mass is 'm' g and specific heat is 's' $cal{g}^{-1}{C}^{-1}$ is given by ..............

Answer 1

The water equivalent means the amount of water that requires the same quantity of heat to raise its temperature by as the body needs for rise in temperature.

Water equivalent$=$mass $\times$ specific heat$=mg\times scal{g}^{-1}°C^{-1}=mscal°C^{-1}.$
