Black Hole Thermodynamics

  • #1
Hawking showed that black holes dissipate energy when virtual particles are "emitted" by black holes and therefore black holes evaporate. However it seems to me that a shrinking black hole means a decrease in entropy and thus a violation of the second law of thermodynamics; is this the case?

Hawkings didn't do this. Hawking did,

Freezing water does the same thing.

nd thus a violation of the second law of thermodynamics
Does freezing water violate the second law? If not, why not? And does the same explanation apply to black holes?
