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).
