Homework Statement
Consider a small portion (area=A) of the inside wall of a container full of gas. Show that the number of molecules colliding with this surface in a time interval Δt is PAΔt/(2mvx avg), where P is the pressure, m is the average molecular mass, and vx avg is the average x velocity of those molecules that collide with the wall.
Homework Equations
PV=NkT, 1/2mv2=3/2kT, P=F/A=m(Δv/Δt)
The Attempt at a Solution
The problem here is that I am not entirely sure where to start and would appreciate some hints as to which way to proceed. I have attempted to see relationships between the Ideal Gas Law, temperature-KE equivalence, and the pressure but have yet to succeed. For those who are interested it is Problem 1.22a in Schroeder's Introduction to Thermal Physics.
Thank you very much for any hints and help
