The ideal gas is taken clockwise around the cycle a,b,c, a. The process a-b forms a linear p-V curve between points a and b (ie, it is not an isotherm or an adiabat) P. (101325 Pa = 1 atm) P/2 (1L= 0.001 m³) (R=8.31J/molK = 0.0821 atmL/molK) Cv = 12.5 J/molK 2V. Cp = 20.8 J/molK а. Find the temperatures at points b and c. b. How many gas molecules are in the engine? Calculate the work done on the gas over the entire cycle (a-b-c-a) с. What is the change in thermal energy of the gas over the full cycle (a-b-c-a). Explain/Justify your answer. d. е. Which process/processes (a-b, b-c, or e-a) require heat to be added to the gas? Explain/Justify your answer. f. Calculate the change in thermal energy of the gas (in Joules) during process c-a.
