Answer to Question #81526 in Molecular Physics | Thermodynamics for Priya Rater

Question

5.Some mass of a diatomic gas undergoes a compression process twice: first time - isothermally and second time – adiabatically. The gas is returned to the initial state before the second process. Each time the final pressure of the gas is n time greater than the initial pressure. Compare the work done by the gas in these two processes for two cases: n = 2 and n=100.

6.One mole of a monoatomic gas performs a cycle consisting of three processes: adiabatic expansion, isothermal compression, and isochoric heating. What work was done during adiabatic portion of this cycle, if the gas has consumed Q=10 kJ of heat during the isochoric portion? Draw the diagram of the process.

7.Assuming one knows the specific molar heat capacity of a gas at constant volume, calculate the specific molar heat capacity of the same gas in the process where the pressure is reversely proportional to the temperature: P=a/T.
