First of all, WOW!! So helpful! I'm a little confused about the ideal gas problem - So in my ChemE thermo class we talk about the entropy change of an ideal gas as delta S = integral of Cp*dT/T - ln(P/P0)*R. Now this would equal zero for a reversible process, but nowhere in the problem does this say that it is reversible and the only ispentropic processes are reversible and adiabatic. I'm not sure what to think because your reasoning makes sense here but I'm sure if you have an irreversible adiabatic process there's an entropy change, as all irreversible processes have entropy changes. This is quite a thinker...

When work is done on the system, to compress the gas, the work is positive because it is added into the system.

@carultch Жыл бұрын

There are different sign conventions. The heat engine sign convention assigns work as positive when the system provides the work, and heat as positive when it is added to the system.
