WebMar 26, 2024 · The primary function of a stirring rod is to stir solutions by hand. Stirring rods have other uses in the laboratory, however, including helping to decant liquid from containers, breaking up emulsions and inducing crystallization. Stirring rods are used to decant or pour liquids slowly. WebA coffee cup calorimeter is made out of two nested styrofoam coffee cups and a lid. The lid contains holes big enough to insert a thermometer and a stirring rod. In this experiment we will weight an empty big test tube then fill it half full with a sample of an unknown metal and weigh it again. We will heat this unknown metal by placing the big sick and tired of being sick and tired book
