Asked by Kay
If 395 grams of water at 21 Celsius absorbs 285kJ of heat from a mountain climbers stove at an elevation where the boiling point of water is 87 Celsius, is this amount of energy sufficient to heat the water to its boiling point? How many kJ are required to boil the water?

q needed to raise T of water from 21 C to 87 C is
q = mass water x specific heat water x (Tfinal-Tinitial).
I get approximately 110 kJ. Is that enough?
