Entropy is not energy; entropy is how the energy in the universe is distributed. There is a constant amount of energy in the universe, but the way it is distributed is always changing. When the way the energy is distributed changes from a less probable distribution (e.g. one particle has all the energy in the universe and the rest have ...

The third law of thermodynamics defines absolute zero on the entropy scale. Third law: The entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 K). The crystal must be perfect, or else there will be some inherent disorder.
WebFor your first question, entropy would increase if a star explodes because all of the tiny particles and molecules would move out (explode) which would mean that there is more variation of the molecules. For example some molecules would be on the right and some would be on the left. As the star explodes the molecules would be all over the place ...
