Question

A cylindrical gas chamber has a piston at one end that can be used to compress or expand the gas. If the gas is initially at 1.22 atm when the volume is 7.26L, what will the pressure be if the volume is adjusted to 3.60L?

Answer 1

The final pressure of the gas will be = 2.46 atm.

Calculation of final pressure

The initial pressure(P1) = 1.22atm

The initial volume(V1)= 7.26L

The final volume (V2)= 3.60L

The final pressure(P2) = ?

Using Boyle's law = P1V1 = P2V2

Make P2 the subject of formula,

P2= P1V1/V2

P2= 1.22×7.26/3.60

P2= 8.8572/3.60

P2= 2.46 atm.
