A monatomic ideal gas initially fills a V0 = 0.45 m3 container at P0 = 85 kPa. The gas undergoes an isobaric expansion to V1 = 1.4 m3. Next it undergoes an isovolumetric cooling to its initial temperature T0. Finally it undergoes an isothermal compression to its initial pressure and volume.   1) Calculate the work done by the gas, W1, in kilojoules, during the isobaric expansion (first process).    2) Calculate the heat absorbed Q1, in kilojoules, during the isobaric expansion (first process).    3) Write an expression for the change in internal energy, ΔU1 during the isobaric expansion (first process).    4) Calculate the work done by the gas, W2, in kilojoules, during the isovolumetric cooling (second process).    5) Calculate the heat absorbed Q2, in kilojoules, during the isovolumetric cooling (second process).

Question

A monatomic ideal gas initially fills a V0 = 0.45 m3 container at P0 = 85 kPa. The gas undergoes an isobaric expansion to V1 = 1.4 m3. Next it undergoes an isovolumetric cooling to its initial temperature T0. Finally it undergoes an isothermal compression to its initial pressure and volume.

 

1) Calculate the work done by the gas, W1, in kilojoules, during the isobaric expansion (first process). 

 

2) Calculate the heat absorbed Q1, in kilojoules, during the isobaric expansion (first process). 

 

3) Write an expression for the change in internal energy, ΔU1 during the isobaric expansion (first process). 

 

4) Calculate the work done by the gas, W2, in kilojoules, during the isovolumetric cooling (second process). 

 

5) Calculate the heat absorbed Q2, in kilojoules, during the isovolumetric cooling (second process).
