Question

why is vapour pressure higher at high temperature?​

Answer 1

Explanation:

Vapour pressure of a pure compound is the pressure characteristic at any given temperature of a vapour in equilibrium with its liquid or solid form. Vapour pressure is a measure of the ability of a compound to bond with itself; compound molecules that bond well with each other will have a low vapour pressure (less tendency to escape to the vapour phase), while poorly bonding compounds will have a high vapour pressure.

Answer 2

Answer:

As the temperature of a liquid increases, the kinetic energy of its molecules also increases and as the kinetic energy of the molecules increases, the number of molecules transitioning into a vapor also increases, thereby increasing the vapor pressure.
