A large pot is placed on a stove and 1.2 kg of water at 14°C is added to the pot. The temperature of the water is raised evenly to 100°C just before it starts to boil.
(a) What amount of heat is absorbed by the water in reaching 100°C?
(b) The water then boils until all of it has evaporated, turning to water vapor at 100°C. How much heat does the water absorb in this process? Answer in J
