  • question_answer At what temperature in the celsius scale, V (volume) of a certain mass of  gas at \[{{27}^{o}}C\] will be doubled keeping the pressure constant           [Orissa 1993]

    A)                 \[{{54}^{o}}C\] 

    B)                 \[{{327}^{o}}C\]

    C)                 \[{{427}^{o}}C\]               

    D)                 \[{{527}^{o}}C\]

    Correct Answer: B

    Solution :

               \[\frac{{{V}_{1}}}{{{V}_{2}}}=\frac{{{T}_{1}}}{{{T}_{2}}}\because {{T}_{2}}=\frac{{{T}_{1}}{{V}_{2}}}{{{V}_{1}}}={{300}^{o}}K,\frac{2V}{V}={{600}^{o}}K\]                                 \[{{T}_{2}}={{600}^{o}}K={{(600-273)}^{o}}C={{327}^{o}}C\]
