In a Styrofoam cup calorimeter, what is the final temperature when 100. g of iron

at 100. ° C is added to 100. g of water at 20. ° C?

1 answer

heat loss Fe + heat gain by H2O = 0
[massFe x specific heat Fe x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tfinal
