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

    Initial pressure, p1 = 1 bar

    Initial volume, V1 = 500 dm3

    Final volume, V2 = 200 dm3

    Since the temperature remains constant, the final pressure (p2) can be calculated using Boyle’s law.

    According to Boyle’s law,



    Therefore, the minimum pressure required is 2.5 bar.
