if a glass of ice water is at equilibrium, what is its temperature?
3 answers
The same as the environmental temperature of its surroundings..
could it be at STP?
I don't think so. P ok but probably not T. If the glass of ice water is at equilibrium I assume that means some ice and some water are in the glass. If they are at equilibrium (meaning ice is not disappearing(melting) and water is not freezing, wouldn't that mean the glass and contents were at Zero C? And to carry that further wouldn't that mean the surroundings were at zero C?
