Calculating final temperature of a substance

Postby Joann Hernandez 2F » Thu Jan 21, 2016 10:45 pm

When you are given the mass at a certain temperature for substance A, then mass at a different temperature for substance B, are those temperatures correlated to each other and work for both substances (as T initial and T final for both?) If not, how do I find the final temperature of substance B??

Use the temperature provided for each substance as its initial temperature.
Then use Tf in your equation to represent final temperature. Tf will be the same for both substances after the temperatures comes to equilibrium.
Finally, you can combine the two Tf's into one variable and solve.
