A) \[{{319}^{o}}C\]
B) \[{{592}^{o}}C\]
C) \[{{128}^{o}}C\]
D) \[{{60}^{o}}C\]
E) \[{{90}^{o}}C\]
Correct Answer: A
Solution :
\[{{P}_{1}}=P,\,{{V}_{1}}=V,\,{{T}_{1}}=273+75=348K\] \[{{P}_{2}}=2P,\,{{V}_{2}}=\frac{85}{100},\,{{T}_{2}}=?\] \[\frac{P\times V}{398}=\frac{2P\times 85V}{{{T}_{2}}\times 100}\]Þ \[{{T}_{2}}=\frac{348\times 2\times 85}{100}\] \[\therefore \] \[{{T}_{2}}=591.6K={{318.6}^{o}}C\]
