Kinetic Theory Of Gases Question 42
Question: Relation between pressure (P) and energy (E) of gas is
Options:
A) $ P=\frac{2}{3}E $
B) $ P=\frac{1}{3}E $
C) $ P=\frac{1}{2}E $
D) $ P=3E $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ P=\frac{1}{3}Nmc^{2}=\frac{2}{3}\times ( \frac{1}{2}Nm )c^{2}=\frac{2}{3}K.E. $
