P_(1)=1atm is mixed with
2000cm^(3)of oxygen
(O_(2))at pressure
P_(2)=2atm. The volume of the mixture is then changed such that the temperature and pressure in the final state are
T=25\deg Cand
P=1atm, respectively. Please calculate the change of entropy associated with this two-step process if both nitrogen and oxygen behavior as ideal gas. (the gas constant
