November 28‚ 2014 ! ! Physical and Chemical Properties! Purpose/Hypothesis:! • The purpose of this experiment is to investigate the chemical and physical properties of pure chemical substances. A property of a substance is some distinguishing characteristic. Some of the most common physical properties are color‚ odor‚ hardness‚ density‚ melting point‚ boiling point‚ and solubility in various solvents. For all of these properties‚ no chemical change takes place. Chemical properties describe the
