The molar specific heat at constant pressure of an ideal gas is (7/2)R. The ratio of specific heat at constant pressure to that at constant volume is :
Answer & explanation
Correct answer: option 1
CP = \(\frac{7}{2}R\)
⇒ CV = CP – R = \(\frac{5}{2}\) R
\(\gamma = \frac{C_P}{C_V} \)
\(\gamma = \frac{7}{5}\)
