Equal volumes of two monoatomic gases, AandBA and B, at same temperature and pressure are mixed. The ratio of specific heats (cp/cV)\left(c_p / c_V\right) of the mixture will be

Options

  1. A0.83
  2. B1.50
  3. C3.3
  4. D1.67

Correct answer

D. 1.67

Step-by-step solution

For monoatomic gases, cpcV=γ=52R32R\frac{c_p}{c_V}=\gamma=\frac{\frac{5}{2} R}{\frac{3}{2} R}1.67 ∵\because Equal volumes of two monoatomic gases are mixed. ∴γ\therefore \gamma will remain the same.
