If C_p and C_ v denote the specific heats of nitrogen per unit mass...

If Cp\mathrm{C}_p and Cv\mathrm{C}_{\mathrm{v}} denote the specific heats of nitrogen per unit mass at constant pressure and constant volume respectively, then

Options

  1. ACp−Cv=R/28\mathrm{C_p-C_v=R / 28}
  2. BCp−Cv=R/14\mathrm{C_p-C_v=R / 14}
  3. CCp−Cv=R\mathrm{C_p-C_v=R}
  4. DCp−Cv=28R\mathrm{C_p-C_v=28 R}

Correct answer

A. Cp−Cv=R/28\mathrm{C_p-C_v=R / 28}
