Question

0.5 A gas mixture consists of 2 moles of oxygen and 4 moles
argon at temperature T. Neglecting all vibrational modes,
the total internal energy of the system is​

Answer 1

Answer:

We have to find the total energy of the system:-

we know that  f = degree of freedom

as oxygen is a diatomic gas 

diatomic gas degree of freedom  f₁ = 5

monoatomic gas degree of freedom f₂ = 3

These are the degree of freedom of oxygen & argon 

For a gas , the formula is :-

U = μN  = μ  

 U = 2 × 5 × + 4 × 3 × 

U = 5RT + 6RT

U = 11 RT

Hence the total energy of the system is 11 RT .
