The Kinetic energy of molecules,
E = 3/2 * k * T,
If T=0, then E=0.
E = 3/2 * k * T,
If T=0, then E=0.

At -273.15 degree Celsius the internal energy of molecule is becom zero that's Mean molecular movementum is zero hance KE energy becom zero at absolute temperature.

Absolute zero temperature is the temp at which gas occupies 0 volume where the molecular momentum of gases is 0.
So that as molecular momentum is 0 the KE also 0. This condition occurs at 0 kelvin i.e at -273.15 degree. Celsius.
So that as molecular momentum is 0 the KE also 0. This condition occurs at 0 kelvin i.e at -273.15 degree. Celsius.

The average KE of molecules becomes zero but the KE of some molecules is still non zero hence the statement is false.
