c) Some molecules of a substance have low enough kinetic energy to vaporize. These molecules exert
pressure on the substance.
d) Some molecules of a substance have high enough kinetic energy to melt. These molecules exert pressure on the substance.
Vapour pressure is simply defined as the tendency of a material to change into its vapour state.
Now, vapour pressure is a pressure formed by the vapour of the material in question be it liquid or solid and over the surface of the material in question.
This vapour pressure increases with temperature and we know that as temperature increases, kinetic energy increases and as a result it means that some molecules will posses high kinetic energy to vaporize and these molecules will exert pressure on the substance.
