    Distribution Speed
AI Thread Summary
The Maxwell-Boltzmann speed distribution applies primarily to ideal gases when quantum effects are negligible, meaning it is not universally applicable to all gases. It is specifically valid for mono-atomic gases, while polyatomic gases exhibit additional complexities due to their degrees of freedom. When quantum effects become significant, the behavior of gases must be described using Bose-Einstein or Fermi-Dirac distributions, which account for the differences between bosons and fermions. Therefore, the Maxwell-Boltzmann distribution does not hold for all ideal gases. Understanding these distinctions is crucial for accurately describing gas behavior under various conditions.

Does the Maxwell-Boltzmann speed distribution hold for all ideal gases or just for the mono-atomic ones? If it holds for all gases, why? What happens with the degrees of freedom, don't they change things?? I'm very confused.

It certainly doensn't hold for all gases. The Maxwell-Boltzmann distribution only holds when quantum effects are negligible. When that condition is not satisfied then the difference between bosons and fermions must be taken into account. Hence, the Bose-Einstein and Fermi-Dirac distributions.
 
Does it hold for all ideal gases, even if they are not mono-atomic?
 

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...
