I have a question I hope someone may be able to answer.(adsbygoogle = window.adsbygoogle || []).push({});

I am currently working out an adiabatic compression process that gives me an initial pressure,volume, and temperature. Along with a final pressure and given that the cylinder/piston assembly does not conduct any heat. Another given is that the Cp=3.5R

I have done the work to solve for my gamma and the final volume and temperature for the system. With that I was able to calculate work done by the system which is also the change in internal energy.

My question is how do I find ΔH?

I know that ΔH=ΔU+ΔPV, but I just don't think my way of thinking is correct as I would assume that I would substitute for ΔU=Q-W where I know Q will equal zero.

leading me to an equation of ===> ΔH=dQ-dW+ΔPV leading me to an answer of 0.

Is this a correct assumption? I look forward to any and all productive feed back.

Best Regards,

Dylan
