I Black Hole Thermodynamics

  1. Jun 19, 2016 #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.

    Does freezing water violate the second law? If not, why not? And does the same explanation apply to black holes?
