Homework Statement
Give the physical explanation of the graphs (Fig 4(a) and 4(b)) on Page 4
http://www.pma.caltech.edu/~mcc/Ph127/b/Lecture3.pdf"
Homework Equations
1) Why [tex]V_{g}[/tex] decreases with temperature but [tex]V_{l}[/tex] increases with temperature
2) Why must phase transition happen at constant pressure (Maxwell construction)
The Attempt at a Solution
4(a) As temperature increases, greater proportion of molecules acquire sufficient energy to escape from liquid and consequently a higher pressure is needed to establish equilibrium between liquid and vapour
4(b) don't really know how to explain
