A 40 kg block of ice begins at -40°C. The specific heat of ice is 2090 J/kg*C and the specific heat of water is 4186 J/kg*C. The latent heat of fusion of water is 3.3×10^5 j/kg and the latent heat of vaporization is 2.3×10^6 j/kg. A) How much energy is required to heat ice to the melting point, 0°C?B) How much energy is required to heat the ice from -50°C to the melting point and melt ice?C) How much energy is required to heat ice from -50°C to the melting point, melt the ice & raise temperature of water to 100°C? D) How much energy is required to heat the ice from -50°C to the melting point, melt ice and raise the temperature of water to 100°C then evaporate the water?
