Detailed Solution:(mean free path) =
n → No. of moles in volume v NA ® Avogadro’s Number
The motion of the gas molecules freezes at 0K not 0° C
Average kinetic Energy per molecule per degree of freedom is (for Mono atomic gases)

The average kinetic energy (per molecule)of any (ideal) gas (be it monoatomic like Argon, diatomic like oxygen or polyatomic) is always equal to If depends only on temperature, and is independent of the nature of the gas. So, Answer is 1 : 1.
Degree of freedom, f = 8
So, H =
at constant pressure, W =
150 =
So,
= 5 × 150
= 750 J
To double the Vrms Tf = 4Ti = 4 × 300 = 1200 k.
= 9360 J.
