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.
