Homework Equations
Q=MCdeltaT
The Attempt at a Solution
Since the energy change would be equal but opposite I though oh well I can leave the Q out and have (100.0)4.18(Tf-100.0)=(200)4.18(Tf-20.0). So I sort of did worked through this but started getting crazy stupid answer that I threw away. Pretty much simplified,distributed,addition and subtraction property of equality an then division property of equality
