Question : 1

Total: 23

What will be the minimum pressure required to compress 500 dm3 of air at 1 bar to 200 dm3 at 30°C?

Solution:

According to Boyle’s law, at constant temperature,
P1V1 = P2V2
P1 = 1 bar , P2 = ?
V1 = 500 dm3 , V2 = 200 dm3
∴ P2 =

P1V1

1×500

200

= 2.5 bar. Thus, the minimum pressure = 2.5 bar
