Properties of materials Flashcards
Metals
Shiny
Good conductors of heat and electricity
Opaque
Ductile and malleable
Non-metals
Dull
brittle
Poor conductors of heat and electricity
Metalloids
Shiny or matt
conduct heat and electricity
Conductivity increases when they’re heated
Electrical conductor
A substance that allows an electric current to pass through it
Difference between metalloids and metals
Their conductivity increases with an increase in temperature
Thermal conductor
A material that allows energy in the form of heat to move easily through the material
Ferromagnets
Materials that are strongly attracted to magnets
Magnetic alloys
Ferromagnets that are sometimes mixed with nonmetals to obtain magnetic substances
Different ferromagnets
Hard magnetic material
Soft magnetic material
Hard magnetic material
Materials that take long to magnetise but reserves magnetism and are used for permanent magnets
Soft magnetic material
Materials that are easily magnetised and used as temporary magnets
Uses of magnetic materials
Used in loud speakers and compasses
