Joseph asks:
Is the online Omni calculator correct as a combined gas law calculator?
I saw that adiabatic expansion work was greater than corresponding compression to bring it back to its initial volume.
But this observation for nitrogen and some non ideal gases indicates a work output. If we introduce a hot reservoir and run it in cycles it makes a perpetual motion machine of 2nd kind without a cold reservoir.
Can anyone help Joseph out?
