Explain third law in simple language to understand better

Dear student
THIRD LAW OF THERMODYNAMICS
This is the law which defines absolute zero as the condition for
an entropy of a system to be zero
The third law of thermodynamics states that at absolute zero (0
K or -273 15 oC), the entropy of a perfectly crystalline
substance is zero
The third law of thermodynamics states that the entropy of a
perfectly crystalline substance approaches zero as the absolute
zero of temperature is reached
At lower temperature, the energy of the molecules would be less
Hence the translational, rotational and vibrational motion of the
molecules would be restricted because of which their entropy would
be less and approach zero at extremely low temperature (close to
zero)
Hope it is clear
Regards
