Re: The Third Law

The third law of thermodynamics is basically as the temperature reaches absolute zero (0 Kelvin) then entropy will also decrease to zero.

Re: The Third Law

It is because entropy is the disorder in the universe, so as temperature approaches absolute zero, there is less and less disorder. You can think of it as high temperature is a higher state of disorder since molecules are moving more and moving faster, so low temperature would be slower and less movement of molecules causing less disorder.
