A gas undergoes the cyclic process shown in the PV diagram at right. In the process abc, the system absorbs 4500 J of heat. The internal energy of the gas at a is U₁= 600 J. (b) (c) How much work is done on or by the gas from a to b? How much work is done on or by the gas when it goes from b to c? Note that the vertical scale is measured in kilo-Pa-100 kPa -105 Pa [1 Liter = 10³ m³ ] 100 The net heat absorbed by the gas during the complete cycle is 1000 J. (d) Determine the heat entering or leaving in the process c to a 50 Use the First Law of Thermodynamics to determine the internal energy of the gas at c, Uc b 60 Liters
