Conductors and Insulators

Front

What is a conductor?

Back

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

Front

What is an insulator?

Back

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

Front

Why is plastic considered an insulator?

Back

Plastic does not conduct heat well, making it a good insulator for keeping heat in or out.

Front

What happens to heat when it travels through a conductor?

Back

Heat moves quickly through a conductor, transferring energy from one place to another.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

Why are metal parts used in car engines?

Back

Metal parts can withstand high temperatures and conduct heat away from the engine, preventing overheating.

Front

How does laying on the ground help animals cool down?

Back

Heat from the animal's body is transferred to the ground, lowering the animal's body temperature.

Front

Why are refrigerators not made completely of metal?

Back

Metal easily transfers heat, which would warm the inside of the refrigerator, making it less effective.
