Question

At a constant temperature, the pressure of a gas is given as one atmospheric pressure and 5 liters. When the atmospheric pressure is increased to 2 atm, then what is the volume of the gas?

(a) 1 liter

(b) 5 liters

(c) 10 liters

(d) 2.5 liters

The question was asked in an interview for job.

The origin of the question is States of Matter in portion States of Matter of Chemistry – Class 11

Answer 1

The correct choice is (d) 2.5 liters

For explanation I would say: As we know that, Boyle’s law states at a constant temperature, the pressure of a gas is inversely proportional to its volume so P1V1 equals to P2V2 by substituting P1 as one atmospheric pressure V1 as 5 liters P1 as to atmospheric pressure we get V2 as 5/2 that is 2.5 liters.
