Answer» A steel vessel with a bottom thickness $3.2 cm$ is placed on a hot stove. The area of the bottom of the vessel is $0.32 m^{2}$ . The water inside the vessel is at $100^{\circ} C$ and $0.5 kg$ are evaporated every $4$ minute. Find the temperature of the lower surface of the vessel, which is in contact with the stove. (Take latent heat of vapourization, $L_{v} = 2.4 \times 10^{6} J/kg$ and thermal conductivity of steel, $k_{steel} = 50 W/mK$ )
