Kinetic Theory
State Boyle's Law?
Boyle’s Law : Temperature remaining constant the volume of a given mass of dry gas is inversely proportional to its pressure.
=T=Constant
Calculate the degrees of freedom for monoatomic, diatomic and triatomic gas?
The degrees of freedom of the system is given by:- f=3 N-K
where f = degrees of freedom
N = Number of Particles in the system.
K = Independent relation among the particles.
what do you mean by mean free path and write the formula?
In kinetic theory the mean free path of a particle, such as a molecule, is the average distance the particle travels between collisions with other moving particles. The formula still holds for a particle with a high velocity relative to the velocities of an ensemble of identical particles with random locations.
The speed of sound in oxygen (O2) at a certain temperature is 460 ms−1. The speed of sound in helium (He) at the same temperature will be (assumed both gases to be ideal)
