1. Fermentation products diffuse through the membrane by the vapour pressure difference. 2. DM is an odourless crystalline compound with a very low vapour pressure . 3. This occurs when a sample has a high vapour pressure . 4. The vapour pressure of water is pretty high. 5. Solid hydrogen snow is possible if the vapour pressure is lower than the gas density. 6. Water has a very high vapour pressure . 7. The vapour pressure above the curved interface is then higher than that for the planar interface. 8. The performance of the plenum vaporizer depends extensively on the saturated vapour pressure of the volatile agent. 9. Diesel wouldn't be such a worry due to it's much lower vapour pressure . 10. Any fluid can be used, but mercury is preferred for its high density and low vapour pressure .
