(a) A gas undergoes an irreversible adiabatic expansion. Is the entropy change of the gas + environment the same as for a reversible process that leads to the same final state for the gas+environment? Choices: smaller, larger, the same, or it depends (b) A gas undergoes a cycle described on a PV diagram. For a complete cycle, the entropy change of the gas and environment are: Choices: positive for the environment but not necessarily zero for the gas, zero, negative,...
