  1. Vapor

    A vapor or vapour is a substance in the gas phase at a temperature lower than its critical point. This means that the vapor can be condensed to a liquid or to a solid by increasing its pressure without reducing the temperature. For example, water has a critical temperature of 374 °C, which is the highest temperature at which liquid water can exist. In the atmosphere at ordinary temperatures, therefore, gaseous water will condense to liquid if its partial pressure is increased sufficiently. A vapor may co-exist with a liquid. When this is true, the two phases will be in equilibrium, and the gas partial pressure will equal the equilibrium vapor pressure of the liquid.
