Insulators, Conductors, & Heat Transfer

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to pass through easily. Examples include rubber and wood.

Front

What is a conductor?

Back

A conductor is a material that allows heat or electricity to pass through easily. Examples include metals like copper and aluminum.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, a metal spoon getting hot in a pot of boiling water.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). For example, warm air rising and cool air sinking.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. For example, feeling the warmth of the sun on your skin.

Front

Give an example of conduction.

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

Give an example of convection.

Back

An example of convection is boiling water, where hot water rises and cool water sinks.

Front

Give an example of radiation.

Back

An example of radiation is the heat you feel from a campfire without being in direct contact with it.

Front

Is water a good insulator?

Back

No, water is not a good insulator; it is a conductor of heat.

Front

What materials are good insulators?

Back

Good insulators include rubber, glass, and plastic.
