An ideal gas with 7 degrees of freedom begins at a pressure of8.5 atm, temperature of 25 degrees Celsius and volume of 120L.
A) How many moles of gas are there?
B) The gas expands isobarically to 200L. What is the newtemperature?
C) How much work was done in the expansion?
D) By how much did the internal energy increase?
E) What amount of heat flowed into the gas?
G) The gas then depressurizes isochorically to the originaltemperature. How much heat flowed out of the gas?
H) Finally the gas contracts isothermally back to its originalvolume.
I) How much work was done on the gas in the Sketch this thermalcycle on a PV diagram. contraction?
J) How much heat flowed out of the system?
K) What is the efficiency of this thermal cycle?
L) What is the Carnot efficiency for an ideal heat enginerunning between the same high and low operating temperatures?
