Assume ideal gas?

[Kate Zeile 2D]

When calculating entropy changes due to changes in volume and temperature of a gas, do we always have to assume that the gas behaves as an ideal gas?

[Brandon Fujii 1K]

Unless we learn how to calculate the entropy changes for non-ideal gases, I believe that --for this class-- we assume that all gases are ideal gases.

[Shreya Ramineni 2L]

Yes, I think we assume ideal gases unless specified differently.

[snehabhargava]

Yes, because it is an assumption to make calculations easier.

[Isaiah Little 1A 14B]

I believe that we assume ideal gas behavior for the sake of understanding the basis of the concept. Calculating for non-ideal gas behavior before understanding the ideal gas behavior would most likely be more confusing because the former requires more to be taken into account.
