Specific Heat
Comparison of a similar system shows that A1 causes about twice the drop in water temperature as does brass. The cooling slopes before and after support Newton’s Law of Cooling.
Specific Heat
Room temperature A1 is added to hot water. After 210 s, the system has cometo equilibrium and is slowly cooling. A linear fit to the cooling curve allows extrapolation back to find the equilibrium temperature that would have occurred at 131 s when the A1 was added if the system had come to equilibriuminstantaneously. This allows measurement of the specific heat within atapproximately 10%.
