ANSWER

Q1 A sample of a certain mass of an ideal polyatomic non linear gas is expanded against a constant pressure of 1 atm adiabatically from volume 2L pressure 6 atm and temp. 300k to a state where its final volume is 8L. then calculate the entropy change of system in the process.

Q2 2 moles of an ideal monoatomic gas undergoes a reversible process for which P²V=constant. the gas sample is made to expand from initial volume of 1L to final volume 4L starting from initial temprature 300K. Find the value of delta S for the above process. report your answer as X where delta S for system = XRln2.
