# Black Holes Part 2

The mass of an isolated black hole where $$\textbf{J} = 0$$ and $$Q = 0$$ is $$10^{5} M_{\odot}$$.The black hole evaporates through Hawking radiation over a long period of time and reaches a mass of $$10^{3} M_{\odot}$$. The change in temperature of the black hole can be expressed to three significant figures as $$\overline{abc} \times 10^{-13} \text{K}$$. What is the value of $$\overline{abc}$$?

Due to approximation of constants and potential rounding errors, we accept a 2% range of answers for this problem.
