Assignment:
Find the entropy change of an ideal gas and of a van der Waals gas in case of isothermal expansion in which the volume increases by a factor alpha. Also, find the entropy change in case of a free expansion in which the volume increases by a factor alpha.
In case of the free expansion of the van der Waals gas, find the temperature change.
