    A high- altitude balloon is filled with \[1.41\times {{10}^{4}}L\] of hydrogen at a temperature of \[21{}^\circ C\] and a pressure of 745 torr. What is the volume of the balloon at a height of 20 km, where the temperature is \[-48{}^\circ C\] and the pressure is 63.1 torr?

    A) \[1.247\times {{10}^{5}}L\]    

    B) \[1.66\times {{10}^{5}}L\]

    C) \[1.66\times {{10}^{4}}L\]       

    D) None of these

    Correct Answer: A

    Solution :

    [a] \[\frac{{{P}_{1}}{{V}_{1}}}{{{T}_{1}}}=\frac{{{P}_{2}}{{V}_{2}}}{{{T}_{2}}}\] \[{{V}_{2}}=\frac{745\times 1.41\times {{10}^{4}}\times 225}{294\times 63.1}=1.274\times {{10}^{5}}L\]
