Homework Equations





The Attempt at a Solution


I think I would divide the approximate slope from the beggining by the approximate slope at the end but I'm not sure if that is correct. Also, I do not know how to come up with a number answer.

Latent heat is the heat absorbed or released in going from one phase to another.

In you problem heat is delivered at a constant rate; call it R.
So the heat energy deilvered is equal to the product of this rate R and the time T.

The time taken for the latent heat of fusion is 2. This is the length of the lower flat part of the graph.
The time taken for the latent heat of vaporiation is 7. This is the length of the upper flat part of the graph.

Now divide R*7 by R*2.

There I've almost given you the answer.
