Two identical thermally insulated spherical tanks, A and B, are connected by a valve. Initially tank A contains 20mol of an ideal diatomic gas, tank B is evacuated, and the valve is closed. If the valve is opened and the gas expands isothermally fromA to B, what is the change in the entropy of the gas?
