heat lost by Au bar + heat gained by H2O = 0
[mass Au x specific heat Au x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tfinal.
A 4.0 kg gold bar at 97C is dropped into 0.27 kg of water at 22C.
What is the final temperature? Assume the
specific heat of gold is 129 J/kg C.
Answer in units of C.
