Asked by Tom

60.0 g of iron that has an initial temperature of 250 degrees C and 60.0 g of gold that has an initial temperature of 45.0 degrees C are brought into contact with one another. Assuming no heat is lost to the surroundings, what will be the temperature when two metals reach thermal equilibrium? The specific heat capacity of iron = 0.449 J/g* degrees C and gold = 0.128 J/g* degrees C.

sph = specific heat
heat lost by Fe + heat gained by Au = 0

[mass Fe x sph Fe x (Tfinal-Tinitial)] + [mass Au x sph Au x (Tfinal-Tinitial)] = 0
Solve for Tfinal
