A one pound piece of iron was heated to 1000 °C
and then quenched in a bucket containing one gallon
of water at 25 °C. What was the temperature of the
water after the iron and the water came to thermal
equilibrium? correct answer is 37C

heat lost by Fe + heat gained by water = 0
[mass Fe x specific heat Fe x (Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
Solve for Tf.
