Question

P(Pa) 385 moles of ileal gas undergs tke cyclic proces eneryies at A and 8 are 4.810- B Ac A. The internal J and 4.20 xlo6 T, 3.0x106+ .80 xlo rerpechvely, and B-C is isobaric. V(rn?) 0.200 0 100 (a) What is the qas temperature at A? at is the volume at B if the temperature is 75c lower Than at A? () How much heat does the gas absorb from A to B? (a) Tf thegas lases 3.78 xro Jofhest frm B to C, calculate tha internal energy at C. (t) ?f.wsxto5Jtheatenterthe garfrem C+oA)what is tlewo k doe b the as from C+ A? sfe 3.31

Explanation / Answer

Hi, I am a bit confused about the question. It clearly says that the gas absorbs heat in the process A to B so it expands as it has been clearly shown in the figure that VB > VA. Then how can the temperature at point B be lower than point A by 75 degree celsius???
