Faulty barometer contain certain amount of air and saturated water vapour is known as faulty baromer .
Saturation vapour pressure is a funtion of term only the temparature .The evapouration can be calculated S(vapour)=H(vapour)/temparature
over the surface of the solutin is smaller than that over the pure component And also fautly barometer inside the closed tube is the vapour of saturation
If it is not clarify please serch for reference book
