Heat Transfer GCSE Physics AQA (higher)

A test that i have made on nearly every sentence in P1a.1 in the AQA physics revision guide.

Teacher recommended

?
What is thermal radiation?
the transfer of heat
1 of 22
How does thermal radiation move?
By infa-red waves
2 of 22
What are these waves part of?
The electromagnetic spectrum
3 of 22
The hotter the object, the more/less thermal radiation it emits.
more
4 of 22
What is an example of a vacuum?
space
5 of 22
What is the best absorber of radiation?
dark, matt surfaces
6 of 22
What is the best emitter of radiation?
dark, matt surfaces
7 of 22
Why are most metals good conductors?
They contain free electrons
8 of 22
Why are materials, such as fibreglass, good insulators?
They contain pockets of trapped air
9 of 22
How is heat transferred through a solid?
particles gain kinetic energy and vibrate more.
10 of 22
What happens when metals are heated?
electrons gain kinetic energy and move through the metal, and transfer energy when they collide.
11 of 22
What are poor conductors called?
Insulators
12 of 22
Where does convection occur?
fluids
13 of 22
What happens when a liquid or gas is heated?
It becomes less dense
14 of 22
How does convection occur?
Hot liquid or gas rises
15 of 22
Why do hotter substances rise?
They become less dense
16 of 22
How do we reduce heat loss by conduction?
Trapping a layer of air
17 of 22
How do we reduce heat loss by convection?
Preventing convection currents from being set up
18 of 22
How do we reduce heat loss through radiation?
Using light, shiny surfaces
19 of 22
How do we maximize heat loss?
good conductors
20 of 22
How else do we maximize heat loss?
Painted dull black
21 of 22
How else do we maximize heat loss?
Have more air flow around them

Good quiz but for Q16 convection can occur in both liquids and gases not just liquids :/

Helpful quiz tho thanks :)

Some like it hot

A fluid is a liquid or gas...
but you're welcome :)

Sorry just learn't that yesterday Grace :/ that probably makes me sound really stupid :P I thought i'd come back to this quiz because i knew i commented on a question on fluids :P

sorry again :P

Great Q&A's because there's so many of them and they cover so much important information!

Once you have completed the test, check your answers.

Read the comments people have posted too.

Good for P1 AQA Core GCSE

Great quiz I managed to achieve 68% (17/25) quite proud of that considering I am not good at science! :)
