Molecular flux-thermodynamic kinetics

AI Thread Summary
The discussion focuses on a problem involving molecular flux and thermodynamic kinetics, where a partition divides a volume containing N atoms. The goal is to derive an expression for the number of atoms on each side of the partition over time after a hole is created. The initial solution proposed was N = Noe^(vAt/4V), but it was indicated that this is incorrect as t approaches infinity. Additionally, the impact of having free space on the right side of the partition is questioned, suggesting that the dynamics of atom distribution would change. The conversation emphasizes the importance of accurately applying the equations of molecular flux in thermodynamic scenarios.

Molecular flux--thermodynamic kinetics

Homework Statement



A volume is divided into two equal parts by a partition. The left volume has N atoms. The atoms have a mass m. A hole of area A is made in the partition at time t=0

A)Develop an expression for the number of white atoms on each side of the partition at time t.
B)Check your answer when t-->infinity and when t-->0
C) If the right volume is just free space how is your answer changed?



Homework Equations



\Phi=\Delta/\DeltaA
*\Deltat

Phi= 1/4(v)n where n=N/V

The Attempt at a Solution



i got N=Noe^(vAt/4V) my teacher says this is wrong if i take t-->infinity...im pretty sure what i solved for is correct tho...

Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
