One mole of water vapor is expanded reversibly from 5 L to 15 L at a temperature of 800 K. Calculate q, w, Delta E for this process assuming that water behaves as a van der Waals gas, making use of the formal relation:

Partial stands for Partial Derivative

(Partial E/ Partial V)subscript T = T(Partial P/Partial T)subscript V - P
(&E/&V)t = T(&P/&T)v - P *What it would look like if I had the correct equation and variables.
