PS.5.1.3 (5.P.3.2) #2 Schoolnet (Conductors/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 a good choice for storing popsicles?

Back

Plastic is a poor conductor of heat, which helps keep the popsicles cold.

Front

What makes metal a good conductor of heat?

Back

Metals have free electrons that can move easily, allowing heat to transfer quickly.

Front

Why are baking pans often made of metal?

Back

Metal pans are good conductors of heat, which helps bake cakes evenly.

Front

What happens to the temperature of coffee in a metal mug?

Back

The metal mug retains heat well, so the coffee stays hot longer.

Front

Why are car motor parts made from metal?

Back

Metal can withstand high temperatures better than most plastics, making it suitable for engine parts.

Front

What is the effect of metal on the temperature inside a refrigerator?

Back

Metal conducts heat easily, which would warm the inside of the refrigerator if it were made entirely of metal.

Front

What is an example of a poor conductor of heat?

Back

Wood is an example of a poor conductor of heat, making it a good insulator.

Front

How does insulation help in everyday objects?

Back

Insulation helps keep heat in or out, such as in refrigerators or insulated mugs.
