MATERIALS
Properties of materials
Physical properties
These properties relate to how matenals react to external stimuli,
Electrical properties
-
Electrical insulation---------Some materials don't conduct electricity,
Acoustic properties
-
Acoustic insulators
Some materials don't conduct sound well,
Magnetic properties
Magnetism
Some metals attract
other metallic materials, iron has this property This allows It to
become a permanent magnet. It
acoustic attracts other ferrous matenals, such as steeL
Other properties
Porosity
This property is related to density, if a material is more porous,
it's less dense.

Materials
Physical process
Is is when a substance changes its state, for example when a metal melts.The chemical composition of the
material does not change.
Quimical process
Is is when a substance is transformed into
a different substame with different charactenstics The
conpossition of the material changes. For example, petrol de-rivatives are transformed to create some types of plastic.
