Kinetic energy of the gas becomes zero and molecular motion also becomes zero

(B) The translational kinetic energy for one mole of an ideal gas is given by $K.E. = \frac{3}{2} RT$. At absolute zero $(T = 0 \ K)$,the kinetic energy becomes zero. Since kinetic energy is directly related to the motion of particles,at $0 \ K$,the molecular motion also ceases and becomes zero.
