Что (кто) такое vapour - определение

A SUBSTANCE IN THE GAS PHASE AT A TEMPERATURE LOWER THAN ITS CRITICAL POINT
Vapour; Vapor phase
  • Liquid–vapor equilibrium
  • Invisible water vapor condenses to form visible water droplets called mist
  • equilibrium]]
  • equilibrium]] value, it becomes [[supersaturated]] and [[condenses]] on any available [[nucleation]] sites e. g. [[particles]] of dust. This principle is used in [[cloud chamber]]s, where particles of [[radiation]] are visualized because they [[nucleate]] formation of water droplets.

Vapor

In physics, a vapor (American English) or vapour (British English and Canadian English; see spelling differences) is a substance in the gas phase at a temperature lower than its critical temperature, which means that the vapor can be condensed to a liquid by increasing the pressure on it without reducing the temperature of the vapor. A vapor is different from an aerosol. An aerosol is a suspension of tiny particles of liquid, solid, or both within a gas.

For example, water has a critical temperature of 647 K (374 °C; 705 °F), which is the highest temperature at which liquid water can exist at any pressure. In the atmosphere at ordinary temperatures gaseous water (known as water vapor) will condense into a liquid if its partial pressure is increased sufficiently.

A vapor may co-exist with a liquid (or a solid). When this is true, the two phases will be in equilibrium, and the gas-partial pressure will be equal to the equilibrium vapor pressure of the liquid (or solid).
