Internal Energy Homework: Compare & Rank H2 Molecules in Containers

AI Thread Summary
The discussion centers on comparing the internal energies of containers filled with hydrogen (H2) molecules at the same temperature. The proposed ranking options include A=B=C=D, A>B>C>D, C>A>B>D, and D>B>A>C. The consensus leans towards option D, as it suggests that container D, with the highest number of molecules, has the greatest internal energy, followed by a gradual decrease in the other containers. Participants emphasize understanding the distinction between intensive and extensive properties in relation to internal energy. The final agreement confirms that option D is indeed the correct answer.

Homework Statement



Compare the Internal (or Thermal) energies of the different containers sketched below. Choose the correct ranking of the internal energies provided. Each container contains H2 molecules with the shown amount (the number of molecules) at the same temperature.

a) A=B=C=D b) A>B>C>D c) C>A>B>D d) D>B>A>C

Homework Equations





The Attempt at a Solution



I believe the answer is D, because D has a greater amount of molecules, then it gradually decreases.

Sure...the question tries to make you realize whether internal energy is an intensive or an extensive quantity: have you had those concepts?
 
I just want to make sure... D is the correct answer?
 
Yes. Why the doubt?
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
