    A tyre at \[27{}^\circ C\] temperature and at 2 atomspheric pressure. It brusts suddenly, then the resultant temperature will be:

    A) \[-123{}^\circ C\]

    B)                                        \[240{}^\circ C\]

    C) \[27{}^\circ C\]                 

    D)        \[0{}^\circ C\]

    Correct Answer: A

    Solution :

    When tyre brusts then pressure becomes equal to the pressure of atmosphere, \[\frac{{{P}_{1}}}{{{T}_{1}}}=\frac{{{P}_{2}}}{{{T}_{2}}}\] \[\frac{2}{273+27}=\frac{1}{{{T}_{2}}}\] \[{{T}_{2}}=150\,K\] \[=123\,{}^\circ C\]
