SUMMARY
To convert 500 g of water at 20°C to steam at 100°C, two calculations are necessary: first, heating the water to 100°C, and second, vaporizing the water. The specific heat capacity of water is 4.28 x 103 J/Kg/°C, and the latent heat of vaporization is 2.3 x 106 J/Kg. The total energy required can be calculated using the equations Eh = mct for heating and Eh = mLf for vaporization.
