See the graph below for a picture of what is happening in this problem.
Heat is added and the temperature of the water increases.
That is all that is happening. This problem is likely best done with W5P method because it asks for an amount of heat when you are given two temperatures, a mass, and a type of material. The measurements such as the specific heat, the heat of vaporization, or the heat of fusion, the properties of those materials, are all available if you know the type of material. In the special case of water, you should know all of those property quantities . The English units are not commonly used except in some industrial applications, such as air conditioners being rated in BTU's.
