Calculate the work done according to the graph.

AI Thread Summary
The discussion centers on calculating the work done by a gas during expansion on a pV diagram. The user initially calculated the work as 8*10^11 J, while the answer key states it should be 800 J. A participant points out that the user's error likely stems from incorrectly equating one liter to 10^6 cubic meters. The correct conversion should be applied to achieve the accurate result. Clarifying unit conversions is crucial for solving such problems correctly.

Homework Statement



Calculate the work done by a gas as it slowly expands from point A to point B on the pV diagram shown.

Homework Equations


Work=PΔV


The Attempt at a Solution



I calculatate the area under the curve and added both of the areas and I came up with 8*10^11 J and the answer sheet is saying 800J Now i really don't why I am getting the wrong asnwer if I'm doing everything step by step.

Hi ScienceGeek24! :smile:

(try using the X2 button just above the Reply box :wink:)

Your method is correct, but you seem to be saying that litre is 106 cubic metres. :biggrin:
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
