Q. The saturation vapour pressure of water at $100℃$ is
A) $739\ mm$ of mercury
B) $750\ mm$ of mercury
C) $760\ mm$ of mercury
D) $712\ mm$ of mercury
Explanation
(c) At boiling point saturation vapour pressure becomes equal to atmospheric pressure. Therefore, at $100℃$ for water. $S.V.P. = 760\ mm\ of\ Hg\ (atm\ pressure)$
