Document Summary
Ersc 2220 lecture section 3 the properties of matter and energy. List and define several properties of matter and distinguish them as physical or chemical. Calculations involving the density of liquids and solids. Describe the differences in properties between a pure substance and a mixture. Calculations involving percent as applied to mixtures. 3-1 the physical and chemical properties of matter. Properties describe the particular characteristics of a substance. Pure substances have definite composition and definite, unchanging properties. Physical properties can be observed without changing the substance. Chemical properties require that substance to change into another. Gas neither definite volume or shape. Melting point or freezing point: temperature at which a substance changes from a liquid to a solid or vice versa. Boiling point or condensation point: temperature at which a substance changes from a liquid to a gas or vice versa. Intensive properties those properties that depend on the type of material present.
