Question

methane gas at 550 K and 5 bar undergoes a reversible adiabatic expansion to 1 bar. Assuming methane to be an ideal gas at these conditions, find its final temperature.

Answer 1

Answer:

Using Gay Lussac's Law,

            P1/T1=P2/T2

            5/550=1/T2

                5T2=550

         ∴Final Temperature T2=550/5

                                                =110 K
