A student places 50.0 g of lead, Pb, in boiling water. After several minutes, the student quickly removes the lead and places it into a coffee cup calorimeter containing 100.0 g water at an initial temperature of 27.2°C. If the final temperature of the lead and water together is 28.3°C, what is the specific heat of the metal?

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...

A 500-g chunk of an unknown metal, which has been in boiling water for several minutes, is quickly dropped into an insulating Styrofoam beaker containing 1.00 kg ofwater at room temperature (20.0 C). After waiting and gently stirring for 5.00 minutes, you observe that the water's temperature has reach a constant value of 22.0C.A) Assuming that the Styrofoam absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specic heat of...

A metal object with mass of 24.0 g is heated to 97.0 °C and then transferred to an insulated container containing 88.5 g of water at 20.5 °C. The water temperature rises and the temperature of the metal object falls until they both reach the same final temperature of 23.2 °C. What is the specific heat of this metal object? Assume that all the heat lost by the metal object is absorbed by the water. specific heat:
