Question

A 3.2 L sample of a gas at 2 atm of pressure is expanded until its volume is 5 L. What will be thepressure in atm of the expanded gas sample? Include proper units (abbreviated). Round your answer to two decimal places.

Answer 1

1.28atm

Explanations:

According to Boyle's law

P1V1 = P2V2

where

P is the pressure

V is the volume

Given the following

P1 = 2atm

V1 = 3.2L

V2 = 5L

Required

Final pressure P2

Substitute

P2 = P1V1/V2

P2 = 2*3.2/5

P2 = 6.4/5

P2 = 1.28atm

Hence the pressure in atm of the expanded gas sample
