How much heat (in joules) is required to raise the temperature of 34.0 kg of water from 24 ∘C to 89 ∘C? The specific heat of water is 4186 J/kg⋅C∘. Express your answer using two significant figures.
It takes 1 kcal to raise the temperature of 1 kg of liquid water by 1 C, but only 0.5 kcal to raise the temperature of 1 kg of ice or water vapor by 1 C. Also, it takes 80 kcal to melt 1 kg of ice sitting at 0 C, and 540 kcal to evaporate 1 kg of liquid water sitting at 100 C. 1) How much heat is required to melt 2 kg of ice at 0 C?...
