Thermodynamics Question 41
Question: In an adiabatic process, the state of a gas is changed from $ P _{1},V _{1},T _{1}, $ to $ P _{2},V _{2},T _{2} $ . Which of the following relation is correct
[Orissa JEE 2003]
Options:
A) $ P’=P $
B) $ P’=2P $
C) $ P’=P\times {{(2)}^{15/2}} $
D) $ P’=7P $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \frac{P _{2}}{P _{1}}={{( \frac{V _{1}}{V _{2}} )}^{\gamma }}\Rightarrow \frac{P’}{P}={{(8)}^{5/2}}\Rightarrow P’=P\times {{(2)}^{15/2}} $
