Energy Transfers: Particles

Question 1

A metal is a….

Answer 1

Good conductor of energy

Question 2

Ehat is it called when energy is transferred very quickly?

Answer 2

Conduction

Question 3

Ehat can energy be transferred by?

Answer 3

Conduction, convection and radiation

Question 4

How do particles trasnfer energy in conduction?

Answer 4

By colliding with other particles when they vibrate

Question 5

Name some porr conductors?

Answer 5

Wood, non-metals

Question 6

Heat is it called when something isnt a good conductor?

Answer 6

An insulator

Question 7

What is an insulator?

Answer 7

They are bad condcutors at all that energy is transferred very slowly

Question 8

Are liquids good or bad conductors?

Answer 8

Bad

Question 9

Why do gases not conduct well at all?

Answer 9

There particles are much further apart than solids

Question 10

Convection using soup:

Answer 10

The soup that is in constct with the bottom of the saucepan get hotter so the particles move faster

The particles in the hotter soup move further apart, so the soup becomes less dense.

The hotter soup rises and the coller. Denser soup takes its place

Question 11

Ehat is that process using soup called?

Answer 11

Convection current
