Further, the more energy applied (the hotter the burner), the faster your water is boiled, and the faster it is expelled into the atmosphere as vapor. Similarly, with propane, a warmer ambient temperature (above -44 F) results in a higher rate of vaporization and greater vapor pressure, allowing you to draw more vapor off the top of your cylinder. The vapour pressure of water is the pressure at which water vapour is in thermodynamic equilibrium with its condensed state. At higher pressures water would condense. The water vapour pressure is the partial pressure of water vapour in any gas mixture in equilibrium with solid or liquid water.
