Thermal Properties Of Matter Question 3
Question 3 - 31 January - Shift 2
A water heater of power $2000 W$ is used to heat water. The specific heat capacity of water is $4200 J$ $kg^{-1} K^{-1}$. The efficiency of heater is $70 %$. Time required to heat $2 kg$ of water from $10^{\circ} C$ to $60^{\circ} C$ is S.
(Assume that the specific heat capacity of water remains constant over the temperature range of the water).
