A gas mixture contain one mole O ₂ gas and one mole He gas. Find the ratio of specific heat at constant pressure to that at constant volume of the gaseous mixture.

Options

  1. A2
  2. B1.5
  3. C2.5
  4. D4

Correct answer

B. 1.5

Step-by-step solution

For mixture of gases, C_V= 3 2 R+ 5 2 R 1+1 =2 RC_P=2 R+R=3 R C_P C_V = 3 2 R R =1.5
