## Main Question or Discussion Point

hi all, i have a confusion about the internal energy change and work done in a isobaric system....

suppose i want to find the delQ in isobaric system in terms of P & V....now i may assume the delW part would be pdv=p(V2-V1)...as i m compressing the gas...

but what happens to the du?

and is the specific heat capacity at const pressure somehow related to the du?

plz help
