1. (a) How much heat transfer is required to raise the temperature of a 1 -kg aluminum pot containing 2.8 kg of water from 30 °C to the boiling point and then boil away 0.9 kg of water? Specific heat of water = 1.00 kcal/kg °C Specific heat of aliminum = 0.215 kcal/kg °C Latent heat of vaporization for water = 539 kcal/kg 1 kcal = 4186 J Q kcal (b) How long does this take if the rate of heat transfer is 500 W? Time, t S
