Question

The figure below is a pressure versus volume graph where the different curves represent different processes done on a gas. Starting at the origin to point 1, the pressure and volume are increased to 2736 Pa and 3.74 m3 respectively. From 1 to 2 the gas expands at constant pressure to a volume of 6.74 m3. From 2 to 3 the pressure rises to 4492 Pa. And finally from 3 to 4 the gas expands again to 11.70 m3. Using the ranking module, rank the curves from the most positive to the most negative amount of work done on the gas. Most Positive Work 2-3 0-1 1-2 3-4 4 Most Negative Work hat is the total work done on the gas? V (cubic Number 0-,- 113560464

Explanation / Answer

W01 = (0.5) (height) (base) = (0.5) (2736) (3.74) = 5116.32 J

W12 = (2736) (6.74 - 3.74) = 8208 J

W23 = 0

W34 = (4492) (11.70 - 6.74) = 22280.32 J

so most positive is W34 = 22280.32 J

W04 = W01 + W12 + W23 + W34 = 5116.32 + 8208 + 0 + 22280.32
