Consider 0.446 mole of an ideal gas, initially at temperature 0 "C, pressure 1 atm, volume 10.0 liters, that has five degrees of freedom per molecule. Suppose that this gas is expanded to a volume of 15 liters. What would be the new values of its temperature and pressure if this expansion were
(a) isobaric,
(b) isothermal,
(c) adiabatic?
