International Physics Olympiad Problem from the IPhO 2007 Olympiad.
The problem can be found here: https://s3.eu-central-1.amazonaws.com/physprob.com/files/ipho/2007_Iran_p1.pdf

In this #shorts video the problem consists of finding the rate of change of mass of a black hole while considering its interaction with the cosmic microwave background radiation.
We use E=mc^2 and Stefan-Boltzmann's Law to find the rate of change of mass and find the mass at thermal equilibrium.
This problem is suitable for preparation for the International Physics Olympiad and hard entrance exams like the JEE Advanced, the PAT test for Oxford, Physics Olympiads. Hope this is useful!
