Physical Properties of Matter

1
Physical Properties of Matter

• The properties of a substance that can be
  demonstrated without changing the composition of
  the substance
• Size (length, volume)
• Density
• Mass
• Color

2
Physical Properties

• Melting Point
• Ex. Ice (solid water) starts to melt to liquid
  water at 0 degrees Celsius
• Boiling Point
• Ex. Water boils into steam at 100 degrees
  Celsius

3
Physical Properties

• Malleability can be pounded into a new shape
  without breaking

Metals are malleable
4
Physical Properties

• Iron is malleable

Fe
5
Physical Properties

• Ductility
• Can be pulled into long wires without breaking

Metals are ductile
6
Physical Properties

• Crystal Shape
• Reflects the regular arrangement of atoms in the
  solid

7
Physical Change

• A change in the sample of matter that does not
  result in a NEW substance
• Phase Changes

Changes in shape
Solid liquid gas
8
Chemical Properties of Matter

• How matter behaves when it changes into a NEW
  substance.
• EX. Iron rusts silver tarnishes
• Milk sours sugar ferments
• eggs rot leaves turn
• paper burns

9
Chemical Change

• Substance changes into a NEW substance.
• This change is often an irreversible and
  permanent change in composition

Chemical Reaction

• Chemical changes mean a chemical reaction has
  occurred
• REACTANTS
  PRODUCTS
• old substances become
  new substances
• Sodium Chlorine sodium chloride
• (table salt)
• Na CL NaCL
