If I pour 54 grams of 90 degree Celsius water into a large basin of 0 degree Celsius ice, what can I expect the final temperature of the water to be?
(Given specific heat of water is
(1 cal)/(gram*degree Celsius)
and the heat of fusion is
80 calories per gram
I don't even really need the final answer, I only want to know the steps one takes to get there. I can figure similar problems, but I can't figure this one because there's 2 variables.

Well it's going to be anything between 90 and 0, depending on what "large" means, isn't it?
If there's a million billion tonnes of ice, it's going to be zero to within a rounding error.

hahaha
I tried 0 and it worked
I wasted a lot of time on this question

Q=mc[delta]t + Hf
Balance energies of two separate temps and solve for unknown
