Absolute zero of temperature may be defined as that temperature at which the rms velocities of the gas molecules become zero which is applicable only for ideal gas. Because practically, under extreme low temperature, gases change their stage to liquid much above the abs. temp. and then to solid.

0 Degree Centigrade
Water freezes at 0 degree centigrade, Ice melts at 0 degree centigrade. How can both be true?

It is due to latent heat. When heat is supplied to ice at 0 d cg, this latent heat is utilised to convert the phase of ice into water without increasing the temperture and vice versa.
