What are the effects of environmental pressure on natural selection? A: Environmental pressure is another term for natural selection, a process that encourages some genes to survive because they are conducive to the environment while others die. This process slowly causes a distinct species to evolve over time. Continue Reading.
Vapor Pressure. Definition of the vapor pressure: The partial pressure of a substance in equilibrium with its condensed phase (liquid or solid). The pressure of the vapor over a liquid (solid) at equilibrium.We discussed vapor pressure and/or boiling point in CH301 as it related to intermolecular forces (IMF).Boiling point and vapor pressure are two sides of the same coin.apor Pressure.
