Question

what well be the min pressure required to
compress
500 dm3 of air at I bar to 200 dm3 at 30°C?​

Answer 1

The minimum pressure required is 2.5 bar

Explanation:

Given

Volume of gas V1 = 500 dm3  

Pressure of gas P1 = 1 bar    

compressed volume of gas V2 = 200 dm3

min pressure P2 = ??

Solution

According to Boyle’s Law at constant temperature

P1 V1 = P2 V2

P2 = P1 V1 / V2

P2 = 1 X 500/200

P2 = 2.5 bar  

Hence, the minimum pressure required is 2.5 bar.
