- Please provide solution, thanks.arrow_forwardThe thermodynamic cycle of a heat engine using ideal helium gas is shown in the P-V diagram. The ratio of heat capacities y (also called ratio of specific heats) is the ratio of the heat capacity at constant pressure Cp to the heat capacity at constant volume Cy. For ideal helium gas, y = 1.67. Select the stage that is paired correctly with the process it represents in the P-V diagram. 1-2: adiabatic process O2-3: isochoric process 3-4: isothermal process 4-1: isobaric process p (kPa) 0.8 0.6- 0.4- 0.2 0.0 2 0.2 0.4 0.6 1 0.8 V(m³) 1.0arrow_forwardConsider a process that uses n moles of a monatomic ideal gas operating through a Carnot cycle.

- One mole of an ideal gas is used as the working substance of an engine operating in the cycle shown in the figure below. BC and DA processes are reversible adiabatic.a) Is the gas monoatomic, diatomic or triatomic?b) What is the efficiency and engine?arrow_forwardA monatomic gas is take through a cycle from A to B to C and back to A. At A the pressure is 100,000 pa, the volume is 4.0 liters, and the temperature is 300K. The gas is compressed adiabatically until the volume is 1.0 liters (at B). How much energy was given to or removed from the gas during the adiabatic process?arrow_forwardA certain gasoline engine is modeled as a monatomic ideal gas undergoing an Otto cycle, represented by the p-V diagram shown in the figure. The initial pressure, volume, and temperature are p1 = 1.05 × 105 Pa, V1 = 0.035 m3, and T1 = 290 K, respectively. a)The first step in the Otto cycle is adiabatic compression. Enter an expression for the work performed on the gas during the first step, in terms of V1, V2, and p1. b) Calculate the temperature of the gas, in kelvins, at the end of the first step. c)The fourth and last step in the Otto cycle is isochoric cooling to the initial conditions. Find the amount of heat, in joules, that is discharged by the gas during the fourth step.arrow_forward
