In this experiment, one measures whether it was a physical or chemical process which caused the heat change. Lab Assignment BCA 252. The work term in reactions that do not involve gases is zero, so all of the energy change results in heat. 3- Two sample papers. The reaction is done twice, once to measure the heat of the reaction and again to determine the work done in the system. The amount of heat that flows into or out of the surroundings is determined with a technique called calorimetry (heat measurement). The specific heat of a solution is 4.18J/(g*C °) and its density is … DISCUSSION There are times in the lab when we want to know how much heat is given off or absorbed during a reaction.
