Kinetic Theory Of Gases Question 2
Question: Energy of all molecules of a monatomic gas having a volume $ F $ and pressure $ p $ is 3/2 $ P $ $ V $ . The total translational kinetic energy of all molecules of a diatomic gas at the same volume and pressure is
Options:
A) $ 1/2,PV $
B) $ 3/2,PV $
C) $ 5/2,PV $
D) $ 3,PV $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Energy of mol of gas $ =\frac{f}{2}RT=\frac{f}{2}PV $ Where f= degree of freedom Monatomic or diatomic gases possess equal degree of freedom for diatomic and that is equal to 3, i.e., f=3
$ \
Therefore E=\frac{3}{2}PV $
