its all about vapour pressure.Classical Mechanics Level pending
A jar contains a gas and a few drops of water at T K (temperature). The pressure in the jar is 830 mm of Hg. The temperature of the jar is reduced by 1%. The vapour pressure of water at two temperatures are 30 and 25 mm of Hg. Calculate the new pressure in the jar.
Answer in 3 digits in mm of Hg.
