I'm working through the EK 1001 Chemistry, and am a little confused by a few of their solutions. In two of their solutions they indicate quite explicitly that the work done in a free adiabatic expansion of a gas is zero and that the temperature of an ideal gas undergoing a free adiabatic expansion remains constant.
But I thought that in an adiabatic expansion, you could still have pressure volume expansion doing work and thus a change in internal energy and a change in temperature... You just can't have any heat. Am I missing something or is EK wrong?
