Problem 1 (8 pts) Consider a container of a pure species under two scenarios: 1. The container is vented at 300 K until the last drop of liquid vaporizes and is then sealed again. 2. The container has liquid and vapor in equilibrium and remains sealed. Plot the pressure in the container over the temperature range T = 300, 400 K for each of the following species in the container: Propane, Cyclohexane, Heptane Assume that the vapor behaves as an ideal gas.
