Q13 / 225 · JEE Main 2004 · Chemistry

As the temperature is raised from $20^{\circ} \mathrm{C}$ to $40^{\circ} \mathrm{C}$, the average kinetic energy of neon atoms changes by a factor of which of the following?

  • A
    $1 / 2$
  • B
    2
  • Correct answer
    C
    $\frac{313}{293}$
  • D
    $\sqrt{\frac{313}{293}}$

Solution

$\frac{E_1}{E_2}=\frac{T_1}{T_2}$ $\frac{E_1}{E_2}=\frac{293}{313}$ $\because$ factor $=\frac{313}{293}$

Hence, the correct answer is option: 'C'.
