Problem: The specific heat of water is 1.00 cal/g C, the heat of vaporization of water is 540 cal/g, and the heat of fusion of water is 80 cal/g.  How much heat would be required to convert 10 grams of ice at 0 degrees C to 10 grams of water at 75 degrees C?

We’re being asked to calculate the amount of heat required to convert 10 g of ice at 0 ˚C to 10 g of water 75 ˚C. There are two heats involved in this problem:

1. q1 which is the heat in melting 10 g of ice at 0 ˚C

2. q2 which is the heat in raising the temperature of 10 g of water from 0 ˚C to 75 ˚C


We need to solve for each heat individually then add them together to get the final answer.
