25 04 2017 The Bekenstein Hawking entropy or black hole entropy is the amount of entropy that must be assigned to a black hole in order for it to comply with the laws of thermodynamics as they are interpreted by observers external to that black hole.This is particularly true for the first and second laws Black hole entropy is a concept with geometric root but with many physical consequences.

You can think of Equation 3.5 as a special case of Equation 2.2 If you massage Stokes law Equation 3.3 just a bit by dividing both sides of the equation by μUR to make the equation dimensionless and using the diameter D instead of the radius R you obtain FD μUD = 3π 3.6 Compare this with Equation 3.5 above.

The formula shows that if nothing else changes the volume of a given mass of gas is inversely proportional to the pressure applied to it This relationship is linear if pressure on a gas doubles its volume decreases by 1/2 An alternative expression of the law is PV = C The product of the
