The third law of thermodynamics relates the entropy (randomness) of matter to its absolute temperature. Which of the following statements are in agreement with the third law of thermodynamics?

1.In a gaseous state, the entropy of the system is zero.

2. At the melting point, the entropy of a system increases abruptly as the compound transforms into a liquid.

3.At zero degrees kelvin, substances maximize entropy.

4.At absolute zero, the interatomic distance within a crystal is minimized.

5.In a crystalline state, there is a tendency to minimize entropy.

6.As the temperature of a perfect crystal increases, the random vibrations of the molecules decrease.
