Things I do for coffee (A.K.A., fun with thermodynamics)

I needed hot water at around 80-85 Celsius to use with
At the time, I didn't have a thermometer that goes higher than 50C.
I know the room temperature and the temperature of near-boiling water (close to 100C ).
The result: a calculator, for a cool (pun intended), practical use of thermodynamics.
