    1 L of an ideal gas at \[27{}^\circ C\] is heated at a constant pressure to \[297{}^\circ C\]. Then, the final volume is approximately

    A)  1.2 L                                     

    B)  1.9 L

    C)  19 L                                      

    D)  2.4 L

    Correct Answer: B

    Solution :

                     We know that                 \[\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\] So,          \[{{V}_{2}}=\frac{{{V}_{1}}T{{}_{2}}}{{{T}_{1}}}\] \[\therefore \]  \[\therefore {{V}_{2}}=1\times \frac{(297+273)}{(27+273)}\] \[\Rightarrow \]               \[{{V}_{2}}=\frac{570}{300}\] \[\Rightarrow \]               \[{{V}_{2}}=1.9\,L\]
