Calculate the change in entropy for a system of 2.00 moles of carbon dioxide gas that expands irreversibly from 3.00m3 (the unit of volume is cubic meter) to 6.00m3 (the unit of volume is cubic meter). The temperature of the final and initial state is 300.0 K. (b) [1 mark] What is the change of entropy for the same system as above but for a reversible isothermal expansion from 3.00m3 to 6.00m3 ? Explain your answer in one-two lines. Consider the carbon dioxide gas to behave like a perfect gas. Report your answer in J/K
