What is heat conduction?

• (1) The flow of ice from one object to another

• (2) Heat that flows easily from one object to another as the objects are touching

• (3) Something that resist the flow of heat

• (4) An oven mitt is an example of a heat conductor

Conductors such as metal let ______

flow through easily?

• (1) water

• (2) milk

• (3) heat

• (4) oil

This material property is the ability to resist indentation or abrasion

• Elasticity

• Ductility

• Hardness

• Softness

This material property is the ability to carry electrical current

• Thermal Conductivity

• Electrical Conductivity

• Resistance to corrosion

• Electron Conductivity

A transparent and brittle material:

• Metal

• Sponge

• Glass

• Thermoplastic

Material can conduct heat and electricity, is malleable, and ductile.

• metals

• polymers

• ceramics

• glass

What do materials undergoing plastic deformation do?

• Change their shape when under a load, but return to their original shape when the load is removed.

• Change their shape when under a load, but they remain permanently deformed when the load is removed.

• Break or crumble rather than change their shape under a load.

• Can easily be shaped by hammering or rolling, and they keep their new shape. Some materials can be more easily shaped when heated.
