    As the temperature is raised from \[{{20}^{o}}C\] to \[{{40}^{o}}C\] the average kinetic energy of neon atoms changes by a factor of which of the following                 [AIEEE 2004]

    A)                 313/293               

    B)                 \[\sqrt{(313/293)}\]

    C)                 1/2        

    D)                 2

    Correct Answer: A

    Solution :

               Average kinetic energy \[\propto \] (T Kelvin)                                 (Factor)\[\frac{K.{{E}_{2}}}{K.{{E}_{1}}}=\frac{{{T}_{2}}}{{{T}_{1}}}=\frac{40+273}{20+273}\] \[=\frac{313}{293}\]
