Conduction Convection Radiation

Question 0

What is an insulator

Answer 0

Doesn’t allow heat energy to pass thorough

Question 1

What is conduction

Answer 1

Conduction is when the heat energy travels through a solid

Question 2

What is a conductor

Answer 2

They are objects that let heat pass through them

Question 3

What is convection

Answer 3

When heat energy travels through a liquid or a gas

Eg. Water in a kettle

Question 4

What is infra red radiation

Answer 4

All objects give out and take in thermal radiation, which is also called infrared radiation. The hotter an object is, the more infrared radiation it emits.

Answer 9

Convection- gas and liquid
Conduction- solids
Radiation- doesn’t need a substance

Question 10

What is radiation

Answer 10

I can be a solid liquid or gas
No substance is needed
It can travel through any material, even a vacuum

Question 11
