Answer to Question #174652 in Optics for Vinay

Question

What is the effect of temperature on mean free path in ideal gas?

Answer 1

the Mean free path $(\lambda)$ given by many equations after substituting value of different functions in different forms.

given below is standard form of equation;

MEAN FREE PATH ; $\boxed{\lambda={RT\over\sqrt2 \pi d^2N_AP}}$

from the given equation , when be observe the temperature term independently ;

we can see that mean free path is directly and linearly proportional to temperature, and inversely proportional to pressure .

therefore for effect of temperature we can see that as temperature increase, mean free path will also increase .

$\boxed{\lambda \propto T}$
