(a)

How much heat transfer (in kcal) is required to raise the temperature of a 0.700 kg aluminum pot containing 1.50 kg of water from 35.0°C to the boiling point and then boil away 0.800 kg of water?

? kcal

(b)

How long (in s) does this take if the rate of heat transfer is 550 W (1 watt = 1 joule/second (1 W = 1 J/s))?

? s

Please explain each step thoroughly and why, I am really confused.
