Question
Calculate the final volume of a gas 'X' if the original pressure of the gas at STP is doubled and its temperature is increased three times.

Solution
V1 = X
P1 = 1 atm
V2= ?
T2 = 3 T1
P2 = 2 atm
`("P"_1 "V"_1)/"T"_1 = ("P"_2 "V"_2)/"T"_2`
`(1xx"x")/"T"_1 = (2xx"V"_2)/(3xx"T"_1)`
`"V"_2 = (3xx"T"_1xx"x")/("T"_1xx2) = 1 1/2` times original volume i.e. V1

A fixed volume of a gas occupies 760cm3 at 27°C and 70 cm of Hg. What will be its vol. at s.t.p.
The pressure on one mole of gas at s.t.p. is doubled and the temperature is raised to 546 K. What is the final volume of the gas ? [one mole of a gas occupies a volume of 22.4 litres at stp.]
According to Charles’s law, at constant pressure, the temperature is inversely proportional to volume.
