A gas expands adiabatically at constant pressure such that T ∝ 1 V The value of γ , i.e., C P C V of the gas will be

Options

  1. A1.30
  2. B1.50
  3. C1.70
  4. D2

Correct answer

B. 1.50

Step-by-step solution

T ∝ 1 V T V 1 2 = constant For adiabatic process, T V 1 2 = T V γ - 1 = constant So γ - 1 = 1 2 γ = 3 2 .
