Question

A sample of carbon monoxide gas whose mass is 6.37 g is heated from 25 oC to 192 oC at a constant pressure of 4.12 bar.
Calculate q (in J) for this process. I got an answer of ~1110J




Calculate w (in J) for this process.

I am unsure how to calculate work considering there is no volume.



Calculate ΔE (in J) for this process.
I know this is DE= q + w , but I need to find volume, can someone help me out?

Answer 1

It's a constant volume. Work is =pdeltaV and since delta b is zero, then work is zero.
q = mass CO x specific heat CO x delta T.
You didn't list sp. h. and I don't know all of those by memory.
