Question

60.5 grams of iron at an initial temperature of 87.5 degrees celsius are added to 125 grams of water at an initial temperature of 26.7 degrees celsius. calculate the final temperature of the mixture.

Answer 1

heat lost by Fe + heat gained by water = 0

[mass Fe x specific heat Fe x (Tfinal-Tinitial)] + [mass H2O x specific heat water x (Tfinal-Tinitial)] = 0
