  • question_answer A certain sample of gas has a volume of 0.2 litre measured at 1 atm. pressure and \[{{0}^{o}}C\]. At the same pressure but at \[{{273}^{o}}C\], its volume will be     [EAMCET 1992, 93; BHU 2005]

    A)                 0.4 litres              

    B)                 0.8 litres

    C)                 27.8 litres            

    D)                 55.6 litres

    Correct Answer: A

    Solution :

                    \[\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\because {{V}_{2}}=\frac{{{T}_{2}}}{{{T}_{1}}}{{V}_{1}}\] \[=\frac{{{546}^{o}}K}{{{273}^{o}}K}\times 0.2L=0.4L.\]
