A 196-g aluminum calorimeter contains 530 g of water at 19.8° C. Aluminum shot with a mass equal to 273 g is heated to 100.0° C and is then placed in the calorimeter. Find the final temperature of the system, assuming that there is no heat transfer to the surroundings.

Answer 1

heat lost by Al shot + heat gained by H2O = 0

[mass Al x specific heat A x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0

Substitute all of the numbers and solve for Tfinal.

Answer 2

what is Tinitial for which?

Answer 3

thanks i got it in the end

Answer 4

T final is the same for both.
Tinitial for Al is T it started; Tinitial for H2O is T it started.
