just a random thermodynamics question i was thinking about the other day.

Would stirring sugar into hot coffee cool the coffee or heat it up?

the enthalpy of the sugar mixing with the coffee being negligible. just focused on the energy from stirring. I guess the metal spoon absorbing heat will be negligible also

>does the energy from stirring coffee heat or cool the coffee

room temp being like 25C @ 1atm
