[Tyler]

Less than that of water vapours in air.

[ahtutor]

vapour pressure of a deliquescent substance is less than that of the water vapour in air because these substances absorb water vapor and thus reduce its vapor pressure. Please look at the below table

Systematic name Water vapor

Liquid State water

Solid state ice
