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
