Question

15. What will be the minimum pressure required to compress 500 dm of air at 1 bar to
at 30°C?​

Answer 1

Volume of gas(V1) = 500dm3 (given)

Pressure of gas (p1) = 1 bar (given)

Volume of compressed gas (V2) = 200dm3 (given)

Now ,let P2 be the pressure required to compress the gas.

Therefore at constant temperature P1 V1 = P2 V2 (Boyle’s Law)

As a result P2 = P1 V1 / V2 = 1 X 500/200 = 2.5 bar

Therefore, the minimum pressure required is 2.5 bar.

Answer 2

Answer:

The pressure will be 2.5 bar.
