NEET Physics Thermometry, Calorimetry & Thermal Expansion Question Bank Mock Test - Thermal Properties of Matter

  • question_answer
    The wavelength of maximum energy released during an atomic explosion was \[2.93\times {{10}^{-10}}\] m. Given that Wien's constant is \[2.93\times {{10}^{-3}}\] m-K, the maximum temperature attained must be of the order of

    A) \[{{10}^{-7}}K\]        

    B) \[{{10}^{7}}K\]

    C) \[{{10}^{-}}^{13}K\]

    D) \[5.86\times {{10}^{7}}K\]

    Correct Answer: B

    Solution :

    [b] From Wien's displacement law \[{{\lambda }_{m}}T=b\] \[\therefore T=\frac{b}{{{\lambda }_{m}}}=\frac{2.93\times {{10}^{-3}}}{2.93\times {{10}^{-10}}}={{10}^{7}}K\]
