A silver block, initially at 59.4∘C^\circ C, is submerged into 100.0 g{\rm g} of water at 25.3∘C^\circ C, in an insulated container. The final temperature of the mixture upon reaching thermal equilibrium is 27.6∘C^\circ C.

Answer 1

heat lost by Ag + heat gained by water = 0

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

Substitute and solve for Tf, the only unknown.
