Question

Define absolute zero, according to kinetic interpretation of temperature.

Answer 1

Dear Student,

Absolute zero of temperature may be defined as that temperature at which the rms velocities of the gas molecules become zero.
The value of absolute zero for an ideal gas is -273⁰C.
The gases used in actual practice are far from being ideal, particularly at extremely low temperatures. Before the absolute zero of temperature is reached, all the gases change their state to liquids and then to solids.
