Question

If one Mole of a monatomic gas is mixed with 3 moles of a diatomic gas. What is the molecular specific heat of the mixture at constant volume? 

Answer 1

For, a monatomic gas, Specific heat at consent volume = C_v1 = (3/2)R  ; R = Universal Gas Constant

No. of moles of monatomic gas = n₁ = 1 mole

No. of moles of diatomic gas = n₂ = 3 moles.

 For, diatomic gas, specific heat at constant volume C_v2 = (5/2)R
