Given below are two statements :

Statement (I) : The mean free path of gas molecules is inversely proportional to square of molecular diameter.

Statement (II) : Average kinetic energy of gas molecules is directly proportional to absolute temperature of gas.
In the light of the above statements, choose the correct answer from the option given below:
  1. (A)Statement I is false but Statement II is true.
  2. (B)Statement I is true but Statement II is false.
  3. (C)Both Statement I and Statement II are false
  4. (D)Both Statement I and Statement II are true.✓ Correct

Answer: (D)

Solution

Mean free path — Statement I is true.
Average kinetic energy per mole — Statement II is true.
Both statements are true.
