Answer Posted / monappa
Vaccum pressure is negative pressure exerted under space
that is partially exhausted by artificial means at
respective temperature (such as an air pump).
Vacuum pressure is measured relative to ambient atmospheric
pressure. It is referred to as pounds per square inch
(vacuum) or psiv.
Vapour pressure is the pressure exerted by vapour in
thermodynamic equilibrium with its condensed phases (solid
or liquid) at a given temperature in a closed system.
Its unit is pascal (Pa).
