QNEET-2013-Ph-1508: NEET 2013 Physics - Class 11 NEET-2013-Ph-1508 Solution: The molar specific heats of an ideal gas at constant pressure…

The molar specific heats of an ideal gas at constant pressure and volume are denoted by CpC_p and CvC_v respectively. If γ=CpCv\gamma = \frac{C_p}{C_v} and R is the universal gas constant then CvC_v is equal to R(γ−1)\frac{R}{(\gamma-1)} (γ−1)R\frac{(\gamma-1)}{R} γR\gamma R 1+γ1−γ\frac{1+\gamma}{1-\gamma}

Multiple Choice Options

  • A (γ−1)R{{\left( {\gamma - 1} \right)} \over R} R ( _ _ 1 ) _
  • B γR\gamma R _ R
  • C 1+γ1−γ{{1 + \gamma } \over {1 - \gamma }} 1 _ _ 1 + _ _
  • D R(γ−1){R \over {\left( {\gamma - 1} \right)}} ( _ _ 1 ) R _

Step-by-Step Verified Solution

In case of ideal gas C p � C v = R but _ = C p /C v So, C v = R _ _ 1
