WebExperiment #1: The Cooling Curve of Stearic Acid INTRODUCTION Matter around us exists in three common states-solid, liquid, and gas. Matter can change from one state (or phase, as it is sometimes called) to another. Ice, for example, is the solid state of H 2O. Add energy, and the rigid solid structure breaks down to the liquid state, water. dewalt 616 router motor
