Thermodynamics Question 191
Question: In an isochoric process if $ T _{1}=27^{o}C $ and $ T _{2}=127^{o}C, $ then $ P _{1}/P _{2} $ will be equal to
[RPMT 2003]
Options:
A) 9 / 59
B) 2 / 3
C) 3 / 4
D) None of these
Show Answer
Answer:
Correct Answer: C
Solution:
At constant volume $ P\propto T $
Therefore $ \frac{P _{1}}{P _{2}}=\frac{T _{1}}{T _{2}} $
Therefore $ \frac{P _{1}}{P _{2}}=\frac{300}{400}=\frac{3}{4} $
