I have(adsbygoogle = window.adsbygoogle || []).push({});

P_1 = 1 x 10^5 Pa

p_2 = 11.764x10^5 Pa

V_1 0.826 m^3

V_2 0.142 m^3

and

Expansion / Compression Index of 1.4

I need to calculate.Work Done

First of all i identify 1-2 as an Isothermal Process, which gives equation.

W = P_2 * V_2 * ln (V_2 / V_1)

If i use that formula i get an answer.

What i am unsure of is

1) Am i using the right formula based on what data i have, i only have data that i have above.

2) How and what do i use expansion and compression index for?

Thanks for any help, needed urgent to solve a question.
