Flammability, corrosiveness, reactivity with acid.

intensive Properties: o Independent of the measuring of the substance that is present. Density, boiling point, color. Extensive Properties: o myrmecophilous upon the amount of the substance present. Mass, volume, energy. CHANGES OF MATTER sensual Changes: ? does not alter the composition or identicalness of a substance. Changes of state, temperature, volume, etc. Chemical Changes: ? alters the composition or identity of the substance(s) involved. Combustion, oxidation, decomposition, etc. UNITS OF MEASUREMENT SI UNIT  transnational System of Units (SI) METRIC SYSTEM  record book: 1 cm3 = (1 x 10-2 m)3 = 1 x 10-6 m3 1 dm3 = (1 x 10-1 m)3 = 1 x 10-3 m3 1...If you requirement to get a in full essay, order it on our website: Ordercustompaper.com
