Thermodynamics Question 351
Question: Helium at $ 27^{o}C $ has a volume of 8 litres. It is suddenly compressed to a volume of 1 litre. The temperature of the gas will be $ [\gamma =5/3] $
Options:
A) $ 108^{o}C $
B) $ 9327^{o}C $
C) $ 1200^{o}C $
D) $ 927^{o}C $
Show Answer
Answer:
Correct Answer: D
Solution:
[d] $ T{{V}^{\gamma -1}}= $ constant$ \Rightarrow T _{2}=T _{1}{{( \frac{V _{1}}{V _{2}} )}^{\gamma -1}}=927^{o}C $
