By M. Silberberg Chemistry, 8th ed. by W. Whitten, R. Davis, R., M. L. Peck, and G. Stanley. 4 • Fundamental Definitions: Matter and Energy • States of Matter • Chemical and Physical Properties • Chemical and Physical Changes • Measurements in Chemistry: Units and Conversion, Dimensional Analysis • Dalton’s Atomic Theory • Laws (of Mass Conservation, of Definite Composition, and of Multiple Proportions) • Components of Matter: Elements, Compounds and Mixtures Lecture Outline 5 Chemistry – is the study of matter – its properties, the changes it undergoes, and the energy changes that accompany those processes – is the central and fundamental science 6 Matter – anything that has mass and occupies space. Energy – the ability to do work or transfer heat. 7 States of Matter Classical: • Solids • Liquids • Gases 8 9 States of Matter Non-classical: • Plasma • Bose-Einstein Condensate • Liquid Crystals • Superfluids 10 Properties of Matter • Physical Properties – those which the substance shows by itself without interacting with another substance – e.g. density, color, length • Chemical Properties – those which the substance shows as it interacts with, or transforms into, other substance – e.g. reactivity, flammability 11 Properties of Matter • Extensive Properties – amount dependent properties – e.g. mass, volume, energy • In tensive Properties – amount in dependent properties – e.g. temperature, density 12 Changes in Matter • Physical Changes – occurs when a substance alters its physical form, not its composition 13 Changes in Matter • Chemical Changes = Chemical Reaction – occurs when a substance is converted into a...
