A) \[540\,\,mL\]
B) \[350\,\,mL\]
C) \[280\,\,mL\]
D) \[135\,\,mL\]
Correct Answer: C
Solution :
From Charles? law \[\frac{V}{T}=\]constant Where \[V\] is volume, \[T\] us temperature. Given, \[{{V}_{1}}=300\,mL,\,{{T}_{1}}={{27}^{\circ }}C\] \[=273+27=300\,K\] \[{{T}_{2}}={{7}^{\circ }}C=273+7=280\,K\] \[\Rightarrow \] \[{{V}_{2}}=\frac{{{V}_{1}}{{T}_{2}}}{{{T}_{1}}}\] \[\Rightarrow \] \[{{V}_{2}}=\frac{300\times 280}{300}=280\,\,mL\]
