how does transfer of heat energy occur

Question 1

conduction

Answer 1

transfer of heat energy X physical movement of the medium.

Question 2

Good conductor of heat

Bad conductor of heat

Answer 2

Metals

non-metals
fluids

Question 3

Which matter is a better conductor of heat?

Answer 3

Solids
Its particles are arranged more closely to one another. The close arrangement of particles enables transfer of heat energy to occur more quickly.

Question 4

Convection(liquids)

Answer 4

water is heated and expands. The density decreases so the hot water rises. The colder and less dense water sinks. This whole prosses continues until a convection current is set up

Question 5

Convection

Answer 5

transfer of heat energy from 1 place to another by physical movement of a medium.

Question 6

Radiation

Answer 6

transfer of heat energy X a physical medium
