Which one of the following is NOT a correct expression for an ideal gas? [ C _ p = . Molar specific heat of a gas at constant pressure, C _ V = Molar specific heat of a gas at constant volume, = Ratio of two specific heats of a gas, R = Universal gas constant]

Options

  1. AC _ v = C _ p + R
  2. BR = C _ V ( -1)
  3. CC _ v C _ p = 1
  4. DR = C _ p ( -1)

Correct answer

A. C _ v = C _ p + R

Step-by-step solution

C_P and C_V are related as: C_P=C_V+R Hence expression in (A) is not correct.
