Q3 / 9 · NTA Abhyas (JEE Main) 2020 · Physics · Kinetic Theory of Gases

If the average kinetic energy of a molecule of hydrogen gas at 300 K is E, then the average kinetic energy of a molecule of nitrogen gas at the same temperature is

  • A
    7E
  • B
    14E
  • C
    E7
  • Correct answer
    D
    E

Solution

We know that,

Kinetic energy ∝T

In the question, temperature is same in both conditions. So, the kinetic energy in the second condition is E .

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