(A) Mass of ice, $m = 10 \,kg = 10^4 \,g$.Specific heat capacity of ice, $c = 0.5 \,cal \,g^{-1} \,^{\circ}C^{-1} = 2093.4 \,J \,kg^{-1} \,K^{-1}$.Latent heat of fusion of ice, $L = 80 \,cal \,g^{-1} = 334944 \,J \,kg^{-1}$.The total heat energy $Q$ required is the sum of heat to raise the temperature of ice to $0^{\circ}C$ and the heat to melt the ice at $0^{\circ}C$.$Q = m c \Delta T + m L$$Q = 10 \,kg \times 2093.4 \,J \,kg^{-1} \,K^{-1} \times (0 - (-10)) \,K + 10 \,kg \times 334944 \,J \,kg^{-1}$$Q = 10 \times 2093.4 \times 10 + 3349440$$Q = 209340 + 3349440$$Q = 3558780 \,J \approx 357 \times 10^4 \,J$.
