Thermodynamics Question 323
Question: What is true about pressure?
Options:
A) $ p _{1}<p _{2} $
B) $ p _{1}>p _{2} $
C) $ p _{1}=p _{2} $
D) Cannot predict
Show Answer
Answer:
Correct Answer: A
Solution:
[a]$ V=aT+b $ From standard gas equation,
$ p=\frac{RT}{V}=\frac{RT}{aT+b}=\frac{R}{a+b/T} $
As, $ T _{2}>T _{1} $
$ p _{2}>p _{1} $ or $ p _{1}<p _{2} $ 0
