Understanding the Difference Between Chemical Changes and Physical Changes

The purpose of this study is to distinguish physical changes and chemical changes. This uses an experimental method, in which experiment carried out prove data hypotheses regarding physics that will be proven are the factors influence changes, examples also as well significant differences between In research, I used some tools need materials. For research were test tube holders, measuring pipettes, droppers, spirits lamp, clay triangle gauze, beaker glass, tubes rack tubes, watch glass. While for materials needed I2, CuSO4, Mg, HCl, CCl4, KI, wax, H2O.
