Steam at 100°C is used to warm 350 g of water contained in a 300 g aluminum container.  The initial temperature of the water and aluminum is 20°C and after the steam is added, the equilibrium temperature is 50°C. What mass of steam will be required to accomplish this? Specific Heat of steam = 2010 J/kg- oC Specific Heat of water = 4186 J/kg- oC Specific Heat of aluminum = 900 J/kg-  oC Latent Heat of Fusion of ice = 3.33 x 10 5  J/kg Latent Heat of Vaporization of water = 2.26 x 10 6  J/kg
