One mole of a gas having = 7 5 is mixed with one mole of a gas having = 4 3 The value of for the mixture is ( is the ratio of the specific heats of the gas)

Options

  1. A5 11
  2. B11 15
  3. C15 11
  4. D5 13

Correct answer

C. 15 11

Step-by-step solution

n ₁=1 mole, n ₂=1 ~mole , ₁= 7 5 , ₂= 4 3 aligned & n ₁+ n ₂ _ mix -1 = n ₁ ₁-1 + n ₂ ₂-1 & 1+1 _ mix -1 = 1 7 5 -1 + 1 4 3 -1 aligned aligned & 2 _ mix -1 = 5 2 + 3 1 11 2 & _ mix = 15 11 aligned
