Question

Derive an expression for Charles' law from kinetic gas equation.

Answer 1

♠ ANSWER :

❇ An expression for CHARLES ' LAW from Kinetic gas equation :

Relation between Temperature and mean molecular Kinetic energy.

E = 3/ 2 kT ( k = Boltzman constant ).

pV = 2 / 3 E (k)

E ( k) ∝ T

pV ∝ T

At constant pressure,

➥ V ∝ T.

Answer 2

Heyaa!!
Here is your answer.....
Charles Law Formula. ... At very high temperatures and low pressures, gases obey Charles'law. Derivation: Charles' Lawstates that at a constant pressure, the volume of a fixed mass of a dry gas is directly proportional to its absolute temperature.
