There are two possible ways to heat a substance in the lab. If you are heating something in a large container, you should put it on a hot plate, which is a device which converts electrical energy into thermal energy. If you are using a test tube, then you should heat it over a bunson burner. Grab hold of the test tube using beaker tongs, and set the bottom of the tube a little above the flame. Point the tube away from yourself and others, as the substance may shoot out without warning. Once done, set it back on the rack.
