If ‘ C p ’ and C v are molar specific heats of an ideal gas at constant pressure and volume respectively, if ‘ λ ’ is ratio of two specific heats and ‘ R ’ is universal gas constant then ‘ C p ’ is equal to

Options

  1. AR γ γ - 1
  2. Bγ R
  3. C1 + γ 1 - γ
  4. DR γ - 1

Correct answer

A. R γ γ - 1

Step-by-step solution

∵ C p = 1 + f 2 . R and γ = 1 + 2 f ∴ C p = 1 + 1 γ + 1 . R C p = γ . R γ - 1
