Pressure of a vapour given off by (evaporated
from) a liquid or solid, caused by vibrating
atoms or molecules continuously escaping from
its surface. In an enclosed space, a maximum
value is reached when the number of particles
leaving the surface is in equilibrium with
those returning to it; this is known as the
saturated vapour pressure.
