Accepted Answer

convection

Answer

conduction

Answer

radiation

Question 23

Why is a frying pan often made from copper?

Accepted Answer

Because copper conducts heat easily

Answer

Because copper is shiny

Answer

Because copper is not magnetic

Question 24

Air is a good thermal insulator because

Accepted Answer

The particles in air are spread very far apart and they don't bump into each other very often making it hard to move energy

Answer

The particles in air are very close together so they can bump into each other easily and move energy easily

Answer

Electrical current moves very easily through the air

Answer

The particles in air are moving so slowly

Question 25

Solids and liquids are better conductors than gasses because

Accepted Answer

The particles in solids and liquids are close together so they can bump into each other easily and move energy easily

Answer

The particles in solids and liquids are spread very far apart and they don't bump into each other very often making it hard to move energy

Answer

The particles in solids and gasses are moving much faster than the particles in air.

Answer

Solids and liquids are always metals and metals are always good conductors
