Calorimeter constant with copper and water
WebThe simplest calorimeter consists of a thermometer, metal container of water, and a combustion or reaction chamber. Calorimeters were first devised in the mid-1700s and … Webqcal = CΔT where C is the heat capacity of the calorimeter. The change in heat of the water is given by: qwater = cpmΔT where cp is the specific heat of water, which is 4.184 J/gC, m is the mass of water in the calorimeter in grams, and delta T is the change in temperature. The video discusses how to solve a sample calorimetry calculation.
