Ответ:
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.
