thermal conductors and insulators

Heat conductor

A material that allows heat energy to flow through it

Heat insulator

A material that does not allow much heat energy to flow through it

Example of conductor

The metal on the iron

Example of insulator

The plastic in the cooler

Metals are some of the best conductors of heat this means

Heat can easily flow through metals from a heat source to an object

Why does energy from the coffee transfer to the air, instead of the other way around

Because thermal energy transfer always flows from hot to cold

What would happen if you left a wooden spoon in the hot pot on the stove then touch the spoon

Heat wood not flow easily through the wooden spoon

Good conductors that allows heat transfer

Metals

Good conductor

Silver

Insulators examples

Paper and plastic

Conduction

Direct contact between molecules

Convection

Up and down movement of fluids due to difference in temperature. Examples, boiling water, lava lamp, water cycle

Radiants

Transfer of heat through electromagnetic EM waves examples sun heats up earth, microwaves, and campfire.
