vapour pressure

noun

1. physics the pressure exerted by a vapour. The saturated vapour pressure is that exerted by a vapour in equilibrium with its solid or liquid phase at a particular temperature

Example Sentences

"During storage and shipping these components absorb moisture. Then during the soldering process, when you want to combine the electronic components together, the temperature rises and it creates vapour pressure - it creates a crack."

From BBC

For example, membrane distillation uses a vapour pressure gradient created by the temperature difference across the membrane to transport water vapour through microporous hydrophobic membranes.

From Nature

The two forms, rhombic and monosymmetric, can exist in equilibrium at 95.6�, the transition point at which they have the same vapour pressure.

From Project Gutenberg

Thermodynamic theory also indicates a connexion between the osmotic pressure of a solution and the depression of its freezing point and its vapour pressure compared with those of the pure solvent.

From Project Gutenberg

It also has a much lower, and more uniform, vapour pressure than petrol—to prevent the fuel from vaporising as the air pressure drops with altitude.
