Kinetic Theory Of Gases Question 106
Question: Equation of gas in terms of pressure (P), absolute temperature (T) and density is
Options:
A) $ \frac{P _{1}}{T _{1}d _{1}}=\frac{P _{2}}{T _{2}d _{2}} $
B) $ \frac{P _{1}T _{1}}{d _{1}}=\frac{P _{2}T _{2}}{d _{2}} $
C) $ \frac{P _{1}d _{2}}{T _{1}}=\frac{P _{2}d _{1}}{T _{1}} $
D) $ \frac{P _{1}d _{1}}{T _{1}}=\frac{P _{2}d _{2}}{T _{2}} $
Show Answer
Answer:
Correct Answer: A
Solution:
[a] $ PV=\mu RT=\frac{m}{M}RT $
Therefore $ P=\frac{d}{M}RT $ (Density $ d=\frac{m}{V} $ )
Therefore $ \frac{P}{dT}= $ constant or $ \frac{P _{1}}{d _{1}T _{1}}=\frac{P _{2}}{d _{2}T _{2}} $
