How does wool act as an insulator?

Back

Wool traps heat and prevents it from escaping, keeping the body warm.

Front

Why are copper and plastic used in electrical wires?

Back

Copper is a good conductor of electricity, while plastic is a good insulator, preventing electric shocks.

What is the role of an insulator in temperature regulation?

Back

An insulator helps maintain an object's temperature by preventing heat transfer.
