Properties of Matter

Date

Physical PropertiesGet out your half sheet of paper with

descriptions from yesterday.Share…Characteristics that can be observed or

measured without changing the sample’s composition.

Examples: mass, volume, color, texture, shape, melting point, boiling point, density, solubility and magnetism. Need any defined? Density = mass / volume

Extensive vs. Intensive

Extensive properties depend on the amount of substance. Mass, volume, shape

Intensive properties are independent of the amount of substance present. Color, texture, melting point, boiling point,

density, solubility, magnetism

States of MatterDraw the particles of a solid, liquid and

gas.

We use three ways to determine states of matter: the periodic table, common sense, and prior knowledge.

States of Matter cont.

Solids – maintain their shape and volume (not compressible)

Liquids – fluid in shape, but maintain volume (not compressible)

Gas – fluid in shape, and do not maintain volume (compressible)

Practice

Mercury (Hg) Zinc (Zn) Carbon (C) Salt (NaCl) Water (H2O)

Air (N2,O2,CO2)

Alcohol (C2H5OH)

Methane (CH4)

Neon (Ne) Chlorine (Cl2)

Bromine (Br2)

Snickers bar (CHOCoLaTe)

Chemical Properties

Describe the ability of a substance to combine with or change into one or more other substances.

Example: Has the ability to burn or rust.

Properties Vs. Changes

Properties describeChanges actually occur

Physical change

Alters the appearance of a substance, but does not change the composition.

Examples: all phase changes, break, crush, split, crack Melt/freeze Vaporize/condense Sublimation/deposition

Chemical Change

AKA, chemical reactions, involve the changing of one or more substances into a new substance. The new substance has new physical

properties.
