A Metal Sample Of Mass 190 G Is Kept In Boiling Water For 5 Minutes So That The Metal Sample Reaches The Temperature Of 1 (70.65 KiB) Viewed 12 times

A metal sample of mass 190 g is kept in boiling water for 5 minutes so that the metal sample reaches the temperature of the boiling water. Then a student drops the sample in an 80.0 g aluminum calorimeter that contains 200 g of water. The initial temperature of the calorimeter and the water is 22.0°C. The final temperature at equilibrium is 29.4°C. The specific heat of aluminum is 910 J/(kg - C°) and the specific heat of water is 4190 J/(kg.C°). a) Assume there is no external heat exchange. What is the specific heat of the metal sample? b) If the external heat exchange can't be ignored (assume heat flows out of the system into the cooler room), would the specific heat you've calculated in part a) be too large, too small, or still correct? Explain.
