Why temperature less than `0^@K` is not possible ?

Text Solution

Verified by Experts

According to kinetic theory of gases temperature `propC^2_(RMS)` At `T = propC^2`. At T = `0^@K , C^2=0`, i.e, molecular motion ceases and kinetic energy becomes zero As kinetic energy. Cannot be negative, therefore temperature below `0^@K` is not possible.
