Suppose 4 mol of an ideal gas undergo a reversible isothermal expansion from volume V1 to volume V2 = 2V1 at temperature T=400 K. Find (a) the work done by the gas and (b) The entropy change of the gas. (c) If the expansion is reversible and adiabatic instead of isothermal, what is the entropy charge of the gas.
