Latent heat of fusion/latent heat of vaporization

Click For Summary
SUMMARY

The discussion focuses on calculating the latent heat of fusion and vaporization using a graph that represents heat delivery at a constant rate, denoted as R. The time intervals for the latent heat of fusion and vaporization are specified as 2 and 7 units, respectively. The solution involves dividing the total heat energy delivered during vaporization (R*7) by that during fusion (R*2), leading to a definitive ratio that represents the relationship between the two phases. This method provides a clear approach to understanding phase changes in thermodynamics.

The Attempt at a Solution


I think I would divide the approximate slope from the beginning 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.
 
ok thanks
