The water in your home has been temporarily shut off. You want to boil some water for tea but all you have is a block of ice (200 g) in your freezer. You put the ice in a pot and heat it up. It takes 4 minutes to take the ice from (-10 degrees celsius) to (100 degrees celsius). After 8 minutes how much water is left in the pot?
The specific heat of ice is 2100 J/kg*C, the specific heat of water is 4168 J/kg*C and the specific heat of steam is 2010 J/kg*C. The latent heat of fusion for water is 333 kJ/kg and the latent heat of vaporization is 2260 kJ/kg.
