Question

the pressure P of an ideal gas and its planes ke per unit volume are related by the relation

Answer 1

Average K.E per molecule = 3kT / 2

Explanation:

According to the kinetic theory of gases:

P = Nmv^2/3 V

Where  

• V = volume
• m = mass
• N = number of molecules

mv^2 = Twice of kinetic energy.

P = (2 N / 3 ) K.E / V  

PV = 2 /3  

This is the total kinetic energy of the gas.

Form ideal gas law the equation can be written as;

PV = NkT

Where "K" is the Boltzman constant.

Thus average K.E per molecule = 3kT / 2
