Lab 4 - Calorimetry Purpose To determine if a Styrofoam cup calorimeter provides adequate insulation for heat transfer measurements, to identify an unknown metal by means of its heat capacity and to determine a heat of neutralization and a heat of solution. Boiling water in paper cup; cup does not burn. Boiling water in paper cup; cup does not burn. The paper cup is filled 2/3 full with water, above the point where the metal ring holder touches the cup. The cup fits tightly in the ring holder. When a flame is applied to the bottom of the cup, the cup Bunsen Burner Cup is 2/3 filled with water does not burn. The cup burns above the water line. Lab: Crystals
The maximum volume of vegetable was pressed into pint mason jars allowing for a ½" headspace; fill weights were recorded. Lemon juice (¼ cup) was added. Tap water, if needed, was used to top jars to a ½ inch headspace. The jar contents were cooked, packed into hot jars, capped, and processed in a boiling water canner for 15 minutes (Figure 1.).
enough hot water into the cup to make the total mass of the hot water plus ice equal to 100 Remove the test tube and metal from the boiling water bath. Wipe the outside of the test tube with a paper towel to remove the water on the outside of the tube. Quickly but carefully
Experiment 10 - Thermochemistry
Fill one cup approximately 3/4 full with room temperature water. 3. Your instructor will now come to each lab group and pour the boiling water into the second cup. 4. Place the two covers with the bar and thermometers into the hot and cold water cups. 5. When the thermometer in the hot cup STOPS RISING, record this temperature under the time 0 Boiling Water in Paper Cup - Concepts of Physics
