A 360.0-g piece of rebar (a steel rod used for reinforcing concrete) is dropped into 425 mL of water at 24.0 °C. The final
temperature of the water was measured as 42.7 °C. Calculate the initial temperature of the piece of rebar. Assume the
specific heat of steel is approximately the same as that for iron 0.44), and that all heat transfer occurs between the
rebar and the water (there is no heat exchange with the surroundings).
