Kinetic Theory Of Gases Question 91
Question: 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
Options:
A) 8/7
B) 5/7
C) 9/7
D) 7/5
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ C _{p}=\frac{7}{2}R;C _{V}=C _{P}-R=\frac{7}{2}R-R=\frac{5}{2}R $
$ \frac{C _{P}}{C _{V}}=\frac{7/2R}{5/2R}=\frac{7}{5} $
