Q- One mole of an ideal gas is contained in a thermally insulated container that is connected to another container of equal volume that is initially evacuated. The valve connecting the two containers is now opened and the gas allowed to expand isothermally to fill both sides. The new total volume is twice original volume.

a) What is the entropy change for this process?

b) Is this process reversible or irreversible? Why?
