Edit: according to one chegg responder, "data is missing" but this is not true. The data is in the graph, You are expected to make the proper observations from the pressure enthalpy graph and produce the table. I did a problem like this in class with a graph, just like this one--all we had was the question and the graph. I assure you that everything is right there.

Make a table and a graph showing the latent heat of vaporization as a function of temperature. What is the general trend of the data? Make a table and a graph showing the latent heat of vaporization as a function of temperature. What is the general trend of the data
