Vapour pressure generally increases with an increase in what?
Answer and explanation
Correct answer: Temperature
Increasing temperature raises the average kinetic energy of liquid molecules and increases the fraction that can escape into the vapour phase. The equilibrium vapour pressure therefore rises for a given liquid. The age of the liquid, the appearance of the container and the length of its name do not define this thermodynamic relationship under ordinary comparable conditions.
