Typical foams have essentially the same vapor pressure as the corresponding bulk liquid. Aerosols exhibit higher vapor pressure as a result of surface pressure effects. The increase in vapor pressure ranges from negligible to significant as the droplet size becomes smaller. The increase in vapor pressure can be calculated as a function of diameter and surface tension.
Combustible aerosols in air can explode or deflagrate even if they have little or no vapor pressure.
