Solve all given parts of following problem:
Problem: A cylinder of nitrogen gas has a volume of 1.6×104cm3 and a pressure of 110atm.
Part I: What is the thermal energy of this gas at room temperature (20oC)?
Part II: What is the mean free path in the gas?
Part III: The valve is opened and the gas is allowed to expand slowly and isothermally until it reaches a pressure of 1.0 atm. What is the change in the thermal energy of the gas?
Please use as much detail as possible in your answer. Thank you.
