1. The third law of thermodynamics has already been demonstrated to be true by experiment and many scholars' relative demonstrative ways.

2. It is pointed out that the third law of thermodynamics is a possible approach to overcome the singularity difficulty.

3. Lastly, the third law of thermodynamics of black-hole has been completely discussed.

4. The only snag is the Third Law of Thermodynamics, which says it's impossible to go below -459 F.

5. A simple method is introduced to prove the third law of thermodynamics and the statistical exposition has been given for it.

6. Form here we infer that the cosmic censorship hypothesis is just the third law of thermodynamics of black hole.

7. The specific heat measurements at low temperatures also play important roles in the finding of the third law of thermodynamics, the quantum theory of solid and BCS theory for superconducting etc.

8. Until now there is no universally accepted formulation of the third law of thermodynamics.

9. The relation between the synchronization of clock rate and the zeroth law of thermodynamics, and the relation between the singularity theorem and the third law of thermodynamics are pointed out.

9.

10. It is pointed out that the classical ideal gas is incompatible with the third law of thermodynamics, and some discussions ard done.

11. It is pointed out that the van der Waals gas is also incompatible with the third law of thermodynamics as the classical ideal gas.
