Question 3

What are thermal insulators?

Answer 3

Poor conductors of thermal energy

Question 4

What are the three ways heat energy can be transferred?

Answer 4

Radiation, Conduction & Convection

Question 5

What is radiation?

Answer 5

The transfer of energy in a special form of wave that can travel through many material or empty space.

Question 6

Thermal energy is transferred by…

Answer 6

Inferred Radiation.
•Behave like waves
•Can be absorbed and reflected by objects
Radiation from sun

Question 7

What is thermal conduction?

Answer 7

The process of transferring energy through direct collisions between particles. Most metals (especially hold and copper) are excellent heat conductors
Conduction from touching (direct contact- collisions

Question 8

What is convection?

Answer 8

Can take place in liquids and gasses. The warm fluid moves from place to place carrying thermal energy with it
Convections (currents) in boiling water
