Pressure & Kinetic Energy of a Gas

The temperature at which the kinetic energy of oxygen molecules becomes double than its value at 27∘C27^\circ\text{C} is

Show answer and solution

Answer: (c)

  1. KE ∝T\propto T (kelvin).
  2. T1=300T_1 = 300 K, so double KE needs T2=600T_2 = 600 K.
  3. 600−273=327∘600 - 273 = 327^\circC
  4. So the answer is (c) 327∘327^\circC.
