Energy Transfer By Heating

Question 1

What are good absorbers of infrared radiation?

Answer 1

DARK MATT SURFACES

E.g a dark Matt surface will become hotter than the same surface painted shiny white.

Question 2

What’s good reflectors of infrared radiation

Answer 2

LIGHT, SHINY SURFACES

Question 3

What are the three states of matter

Answer 3

Solid, liquid, gas

Question 4

What is conduction

Answer 4

Conduction for example when one end of a solid is heated the particles vibrate more the energy is then passed to neighbouring particles and this will transfer the heat through the solid.
Liquids and gas particles move more than vibrate when heated causing the heat to be transferred slower.

Question 5

What is infrared radiation?

And how we detect it?

Answer 5

Infrared radiation is energy transfer by electromagnetic waves.
All objects emit infrared radiation
The hotter an object is the more infrared it emits.
We detect it with our skin it makes us feel warm
IT CAN TRAVEL THROUGH A VACCUM this is how we get energy from the sun
