What is the work done by an ideal gas in an isobaric process?

[SOLVED] Isobaric process

Hi, need some help with this.

I got to moles of an ideal gas that are heated at constant pressure from T=27 C to T=107C.

How do I calculate the work done by the gas?

I know that for a isobaric process the work is given by

W = p(V2-V1)

Thanks

Oh, I'm sorry. Yeah, I tried W = nRT.

Came out with 1300 J, but the key book says 1330 J.

Using $W = nR\Delta T$, my answer agrees with your text. I would suggest you re-check your calculations.

There, it worked.
