In school, Jarrett learned that salt lowers the freezing point of water. He wants to test this in a home experiment. He adds an equal amount of salt and room-temperature water into three identical containers. Which of the following steps should Jarrett perform next?
A.
Place all three containers outside on a hot day.
B.
Place the containers in separate freezers with different freezing temperatures.
C.
Place the containers in the same freezer.
D.
Place one container in the freezer, one in the refrigerator, and one at room temperature.

I would use calorimetric to determine the specific heat and I would measure the mass of a sample. I would measure the mass of a sample of the substance. I would heat the substance to a known temperature. I would place the heated substance into a coffee-cup calorimeter containing a known mass of water with a known initial temperature. I would wait for the temperature to equilibrate, then calculate temperature change. I would use the temperature change of water to determine the amount of energy absorbed. I would use the amount of energy lost by substance, mass, and temperature change to calculate specific heat.
