The gas expands isothermally until it has a volume of 3.0m3. It then contracts isobarically. It finally further contracts adiabatic cally to return to its original state. 34. What is the volume at the start of the adiabatic contraction? (a) 1.00m3 (b) 1.93m3 (c) 2.19m3 (d) 2.33m3 (e) 3.12m3 35. What is W, the work done by the gas, during the isothermal expan- sion? (a) 0.7 x 105 J (b) 2.2 x 105 J (c) 3.3 x 105 J (d) 4.0 x 105 J (e) 4.7 x 105 J 36. What is Q during the isobaric contraction? (a) -1.1 x 105 J (b) -1.8 x 105 J (c) -2.0 x 105 J (d) -3.3 x 105 J (e) -4.1 x 105 J 37. A heat engine runs following this thermodynamic process. What is its efficiency? (a) 0.02 (b) 0.12 (c) 0.19
