An ice block of mass 2.0 kg at an initial temperature of -9 C is put into a copper pot of mass 2.5 kg containing 5.0 L of water at 21 C. If you heat up the pot, what is the amount of energy (in J) you need to convert all the ice and the water into steam? (Assume that no energy is lost from the system.)

You may need some or all of the following constants: The specific heat of ice is 2200 J/kg C, the specific heat of copper is 386 J/kg C and the specific heat of water is 4186 J/kg C. The latent heat of fusion of ice is 334000 J/kg and the heat of vaporization for water is 2256000 J/kg .
