How much heat energy is needed to convert a mixture of \(20.0 \mathrm{~g}\) of ice and \(35.0 \mathrm{~g}\) of water at thermal equilibrium to steam at \(100.0^{\circ} \mathrm{C}\) ? If this energy were used to lift a truck, to what height could a \(1.00 \times 10^{4}-\mathrm{kg}\) truck be lifted?
