A) \[546{}^\circ C\]
B) \[182{}^\circ C\]
C) \[819{}^\circ C\]
D) \[646{}^\circ C\]
Correct Answer: A
Solution :
We know that for ideal gas\[\frac{{{V}_{1}}}{{{T}_{1}}}=\frac{{{V}_{2}}}{{{T}_{2}}}\] (at constant pressure) \[\Rightarrow \] \[{{T}_{2}}=\frac{{{V}_{2}}}{{{V}_{1}}}\times {{T}_{1}}=\frac{3V}{V}\times 273\] \[=3\times 273\,\,K\] \[\Rightarrow \] \[{{T}_{2}}=819\,\,K=819-273\] \[={{546}^{o}}C\]
