This is to help me understand a problem in the book, I don't want to state the question I'm attempting to solve though I would rather just get a nudge in the right direction conceptually. (I am analyzing an isotherm and adiabatic curve at the same point.)(adsbygoogle = window.adsbygoogle || []).push({});

My book states that for an ideal gas, an adiabatic curve at any point is always steeper than an isotherm passing through the same point: why is this?

Also, the question I'm given does not explicitly state that I'm dealing with an ideal gas, is the ratio of heat capacities still valid for a van der waals gas (which is the only other type of gas that I know how to deal with)? What about the rule i stated above concerning the slopes at a particular point?
