• # question_answer 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 $[\gamma =5/3]$ A) ${{108}^{o}}C$ B) ${{9327}^{o}}C$ C) ${{1200}^{o}}C$ D) ${{927}^{o}}C$

[d] $T{{V}^{\gamma -1}}=$constant$\Rightarrow {{T}_{2}}={{T}_{1}}{{\left( \frac{{{V}_{1}}}{{{V}_{2}}} \right)}^{\gamma -1}}={{927}^{o}}C$
