How would I calculate the work done by the gas molecules?

AI Thread Summary
To calculate the work done by gas molecules, use the formula W = P × ΔV, where W is work, P is pressure, and ΔV is volume change. The pressure of 0.25 atm converts to 25331.25 Pascal in SI units. The volume change is given as 1.7 x 10^-22 m^3. To find the work in joules, multiply the pressure in pascals by the volume in cubic meters. The correct calculation will yield the work done by the gas molecules in joules.

Homework Statement


Hello, I just need help figuring out how to calculate the work done by the gas molecules for my physics homework :)
Formula given: W=Px∆V (W=work, P=pressure, and V=volume)
What I know: So my calculated volume is 1.7x10^-22m^3.
Pressure=0.25 A t m (atmospheric pressure)
I just need help figuring out how I would multiply the two together.

Homework Equations

The Attempt at a Solution


Would I change 0.25 A t m to scientific notation? So it would be 2.5x10^-1, then if I multiplied it by 1.7x10^-22m^3 it would be 4.25x10^-23 Joules of work done?

To get the work in joules, it is best to convert the pressure to SI units (pascal).

But I suspect you are wrong about the volume change.
 
Ok, so 0.25 A t m = 25331.25 Pascal, which is 2.533125x10^4 in scientific notation. Would I then just multiply the two together? And no, I did all my calculations correct, the volume change is 1.7x10^-22m^3, I even had another person on here help me achieve that answer.
 

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'

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...
