An ideal gas is expanding such that p T 2 = constant. The coefficient of volume expansion of the gas is

Options

  1. A1 T
  2. B2 T
  3. C3 T
  4. D4 T

Correct answer

C. 3 T

Step-by-step solution

Given, p T 2 = constant ∴ n R T V T 2 = constant or T 3 V - 1 = constant Differentiating the equation, we get 3 T 2 V . d T - T 3 V 2 . d V = 0 or 3 . d T = T V . d V From the equation, d V = V γ d T γ = coefficient of volume expansion of gas = d V V . d T ∴ γ = d V V . d T = 3 T
