37) A student attempts to determine the specific heat of a metal by conducting a calorimetry experiment. The student heats 250 g of the unknown metal to a temperature of 38 C. They then place the metal into a calorimeter which contains 100 g of water at 21°C. The maximum temperature of the water rises to 27°C. a) What is the heat gained by the water in the calorimeter? Specific heat of water is 4.18 J/g'C. (5 points) b) What...

PART A: A student constructs a coffee cup calorimeter and places 50.0 mL of water into it. After a brief period of stabilization, the temperature of the water in calorimeter is determined to be 19.6 °C. To this is added 50.0 mL of water that was originally a temperature of 54.5 °C. A careful plot of the recorded temperature established T0 as 31.1 °C. What is the calorimeter constant (J/°C)? DensityH2O = 1.00 g/mL Specific HeatH2O = 4.184 J/g·°C PART...
