Hey,
The entropy of a black hole is S = kB (4∏GM2)/(hbar c)
S=Q/T
T= Q/S
T = Q (hbar c)/ (4∏GM2kB)
The temperature derived from hawking radiation is:
T = c3 hbar/ (8 pi G M kB)
Which implies Q = (1/2)M c2
Is this true?
I have found online that the heat should equal to the mass-energy of the black hole,
Mc2
But it was not explained,
Is it correct that Q = (1/2)M c2?
Thanks
