I broke part a) up into two parts like you said, went at it, and got an answer of 5.95oC which is correct! :biggrin: Part b) still evades me at the moment, but I'll work on it some more and let you know. Thank you for all your help and advice!
Ah, thanks for catching the typo. I actually entered the un-typo-ed answer, however, and that didn't work. What exactly is the sign error I made? Could you expound upon that a little bit more? The negative of the energy lost by the water and aluminum should equal that gained by the ice...
My Physics III class is going through basic Thermodynamics and I have hit a bit of an impasse. This is relatively simple stuff, but for some reason, I cannot get this problem right. I've worked on it to the point of confusing myself pretty thoroughly. I would really appreciate some direction...
