Which statement is most correct while studying vapour pressure?
Answer and explanation
Correct answer: Vapour pressure is pressure exerted by vapour at equilibrium in a closed vessel
The equilibrium vapour pressure is the pressure exerted by vapour in contact with its liquid in a closed system at a specified temperature. It reflects a dynamic balance between evaporation and condensation. It is not the weight of the liquid, is not always zero, and changes with temperature, generally increasing as temperature rises.
