What is the pressure exerted by vapour when a liquid and its vapour reach equilibrium in a closed vessel?
Answer and explanation
Correct answer: Vapour pressure
When a liquid and its vapour coexist in a closed vessel at a fixed temperature, evaporation and condensation eventually occur at equal rates. The pressure exerted by the vapour at this dynamic equilibrium is called vapour pressure. Osmotic pressure concerns solvent flow through a semipermeable membrane, while atmospheric pressure is the pressure of the surrounding atmosphere.
