Q. Helium at $27℃$ has a volume of $8\ litres$. It is suddenly compressed to a volume of $1\ litre$. The temperature of the gas will be $\lbrack\gamma = 5/3\rbrack$
A) $108℃$
B) $9327℃$
C) $1200℃$
D) $927℃$
Explanation
(d) $TV^{\gamma - 1} =$ constant $\Rightarrow T_{2} = T_{1}\left( \frac{V_{1}}{V_{2}} \right)^{\gamma - 1} = 927℃$
