(a)
Interpretation:
The vapor pressure for water in
Concept introduction:
Vapor pressure is a pressure exerted by gaseous vapor above a liquid in a sealed container, when the rate of evaporation and condensation are equal. The vapor pressure increases with temperature and when temperature decreases vapor pressure also decreases.
