Entropy of a gas

Postby Leah Thomas 2E » Wed Jan 24, 2018 8:00 pm

Does entropy increase when an ideal gas is compressed isothermally?

Entropy decreases when an ideal gas is compressed because the volume decreases and pressure increases.

Since the volume decreases, there is less space in the container or wherever the gas is contained, therefore the gas has less possible states therefore the degeneracy for the gases decreases and that means that the entropy of the gas decreases.
