I did each one individually, as my teacher taught me to do. I'm not sure if this is what you meant, but I'll show you anyway.
Q1 = mLf = (0.05)(3.4x106) = 17 000
Q2 = mcΔT = (0.05)(4200)(Tf+5) = 210Tf + 1050
Q3 = -mLv = -(0.05)(2.26x106) = -113 000
Q4 = mcΔT = (0.05)(4200)(Tf -160)
Then I...
I sketched a graph, which my instructor looked at. He said it's good and that I'm on the right track, but I don't know what it is I'm doing wrong. I tried fiddling with the positive and negative signs to see if I could at least get a reasonable answer with no luck. I just tried to do it in some...
Homework Statement
You add 50 g of steam at 150 degrees centigrade to 50 g of ice at negative five degrees centigrade. What is the final temperature?
Homework Equations
Q = mLfv
Q = mcΔT
The Attempt at a Solution
Qg = Ql
Q1 + Q2 = -Q3 - Q4
mLf + mcΔT = -mLv + mcΔT [ΔT will be negative, making...
