The vapour pressure of water depends upon?


The vapour pressure of water depends upon temperature.

Vapour pressure

Vapour pressure can be defined as the pressure exerted by a vapour with its condensed phases in a closed system at a given temperature.

  • The equilibrium vapour pressure is a well-known measure of a liquid’s evaporation rate.
  • The propensity of particles to escape from the liquid or a solid is known to be related.
  • The term ‘volatile material’ refers to a substance that has a high vapour pressure at normal temperature.
  • It should be remembered that vapour pressure refers to the pressure exerted by a vapour above a liquid surface.
  • The vapour pressure of the liquid increases with an increase in its temperature. The molecules of the liquid have higher energy at higher temperatures.
