Calculate Degrees of Freedom for 10 cc Oxygen Gas at STP

AI Thread Summary
To calculate the degrees of freedom for 10 cc of oxygen gas at standard temperature and pressure (STP), the equipartition law is relevant. Oxygen, being a diatomic molecule, has five degrees of freedom: three translational and two rotational. The discussion emphasizes the importance of understanding the kinetic theory of gases in this context. Participants seek clarification on applying the equipartition law to determine the degrees of freedom accurately. Ultimately, the calculation hinges on recognizing the molecular structure of oxygen and its behavior under STP conditions.

Can somebody help me out with this??

Calculate the no. of degrees of freedom of 10 cc oxygen gas at Normal temperature and pressure.

This problem is from the kinetic theory of gases chapter.

what ?

are you referring to the equipartition law ?

Yeah I am referring to the equipartition law.
 
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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is(Figure 2): F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...
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...
