Explanation

Question 20 of 28

1

Usually conduction is faster in denser solids, because the particles are closer together and so will collide more often and pass energy between them. Materials that have larger spaces between their particles conduct heat energy much more slowly - these materials are insulators.

Select one of the following:

True
False

Explanation

Question 21 of 28

1

Usually ____ is faster in solids, because the particles are _ and so will more often and pass energy between them. Materials that have __ spaces between their particles conduct _ energy much more - these materials are ____.

Select one of the following:

conduction
denser
closer together
collide
larger
heat
slowly
insulators

Explanation

Question 22 of 28

1

Why are metals good conductors?

Select one of the following:

They have free particles
They have expensive particles
They have free electrons
They have expensive electrons

Explanation

Question 23 of 28

1

Metals conduct so well because the electrons are free to move inside the metal.

Select one of the following:

True
False

Explanation

Question 24 of 28

1

At the hot end of the metal, electrons will move: faster or slower?

Select one of the following:

Faster
Slower

Explanation

Question 25 of 28

1

At the hot end of the metal, electrons will more faster and collide with other free electrons. What happens next?

Select one of the following:

They transfer energy
They transfer electricity
They exchange Christmas cards

Explanation

Question 26 of 28

1

Because the electrons can move freely, this is obviously a much faster way of transferring the energy through the metal than slowly passing it between jostling neighbouring atoms. This is why heat energy travels so fast through metals.

Select one of the following:

True
False

Explanation

Question 27 of 28

1

If a spade is left in the sun and you touch the metal part, it feels much hotter than the wooden handle. This is because the metal is hotter.

Select one of the following:

True
False

Explanation

Question 28 of 28

1

If a spade is left in the sun and you touch the metal part, it feels much hotter than the wooden handle.

IT ISN'T HOTTER - it just conducts the heat into your hand much quicker than the wood, so your hand heats up much quicker.
