    Change Pressure
AI Thread Summary
When the pressure of an ideal gas is changed isothermally, the mean free path is the only factor that changes. The root-mean-square (RMS) speed, internal energy, most probable kinetic energy, and average speed remain constant because temperature does not vary in isothermal conditions. The discussion highlights the importance of understanding the definitions and calculations related to RMS speed and isothermal processes. Clarifying these concepts is essential for accurately interpreting the behavior of gases under varying pressure. Ultimately, the mean free path is the primary variable affected by isothermal pressure changes.

Homework Statement


Which of the following change when the pressure of an ideal gas is changed isothermally? A. Mean free path B. Root-mean-square molecular speed C. Internal energy D. Most probable kinetic energy E. Average speed
correct answer is A
doesn't the rms increases too?

Look up how to calculate the RMS speed from the temperature.
Look up what Isothermal means.

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...
