I don't agree: "defined as the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases (solid or liquid)" but maybe i am missing something. To clarify, I am looking for the pressure exerted on the walls of the container.
I am trying to calculate the increase in pressure caused by liquid nitrogen when it changes from liquid to vapor within a closed, constant volume at atmospheric pressure. How can this be done? Do I need to include the heat of vaporization?
