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
