    The volume of a gas measured at \[\text{27}{{\,}^{\text{o}}}\text{C}\]and 1 atm pressure is 10 L. To reduce the volume to 2L at 1 atm. pressure, the temperature required is

    A)  60 K          

    B)  75 K

    C)  150 K         

    D)  225 K

    Correct Answer: A

    Solution :

     Here \[{{V}_{1}}=10\,L,\,{{V}_{2}}=2L\] \[{{\text{P}}_{\text{1}}}\text{=}\,\,\text{1}\,\text{atm,}\,{{\text{P}}_{\text{2}}}\text{=}\,\text{1}\,\text{atm}\] \[{{T}_{1}}=300\,K,{{T}_{2}}=?\] \[\frac{{{P}_{1}}{{V}_{1}}}{{{T}_{1}}}=\frac{{{P}_{2}}{{V}_{2}}}{{{T}_{2}}}\] \[\frac{1\times 10}{300}=\frac{1\times 2}{{{T}_{2}}}\] \[{{T}_{2}}=\frac{300\times 2}{10}=60\,K\]
