Thermodynamics Question 175
Question: One mole of a perfect gas in a cylinder fitted with a piston has a pressure P, volume V and temperature T. If the temperature is increased by 1 K keeping pressure constant, the increase in volume is
Options:
A) $ \frac{2V}{273} $
B) $ \frac{V}{91} $
C) $ \frac{V}{273} $
D) V
Show Answer
Answer:
Correct Answer: C
Solution:
For isobaric process $ \frac{V _{2}}{V _{1}}=\frac{T _{2}}{T _{1}}\Rightarrow V _{2}=V\times \frac{274}{273} $
Increase $ =\frac{274\ V}{273}-V=\frac{V}{273} $
