Do solids and liquids exert a vapour pressure?

I am not entirely clear as to what you are asking........

Explanation:

Liquids (and some solids) do exert an "equilibrium vapour pressure"...... i.e.

"Liquid "rightleftharpoons" Gas"

The extent of the equilibrium is a function of temperature, and at the liquid's "normal boiling point", the vapour pressure of the solution is 1*atm. At temperatures LESS than the normal boiling point, a vapour pressure will still be exerted. For water, the vapour pressures are extensively tabulated.......and of course must be accounted for when we collect a volume of gas by water displacement.

Sometimes, the vapour pressures are reported in "mm Hg", and thus this measurement can be subtracted from the atmospheric pressure of "760 mm Hg",
