Kinetic Theory of Gases · Kinetic theory of an ideal gas

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R

Assertion A: If the average kinetic energy of H2\mathrm{H_2} and O2\mathrm{O_2} molecules, kept in two different sized containers are same, then their temperatures will be same.

Reason R: The r.m.s. speed of H2\mathrm{H_2} and O2\mathrm{O_2} molecules are same at same temperature.

Choose the correct answer from the options given below

  1. (1)Both A and R are true and R is the correct explanation of A
  2. (2)Both A and R are true but R is NOT the correct explanation of A
  3. (3)A is true but R is false
  4. (4)A is false but R is true
