Question

c.) Calculate the work done on the gas over the entire cycle (a-b-c-a)

d.) What is the change in thermal energy of the gas over the full cycle (a-b-c-a). Explain/Justify your answer.

e.) Which process/processes (a-b, b-c, or c-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.

2. A heat engine contains a monatomic, ideal gas with the cycle shown in the pV diagram. The cycle begins at point a with p,- latm, V,= 10L, and T= 300K. The ideal gas taken clockwise around the cycle a,b,c, a. The is a process a-b Pa forms a linear p-V curve between points a and b (ie, it is not an isotherm or an adiabat) P,/2 b (101325 Pa = 1 atm) (IL= 0.001 m³) (R=8.31J/molK Cv = 12.5 J/molK = 0.0821 atmL/mblK) V 2V Ср 3 20.8 J/molK
