Conduction (energy transfer via contact)
300
What type of heat transfer needed to heat up the spoon?
Convection
300
The handle of most cooking pots are made of rubber because...
they are an insulator, and do not let the heat pass through
300
What method of heat transfer is shown here?
Convection heating (hot fluid rises, cool fluid sinks)
400

400
As water is heated, the particles become __________
slightly separated
400
When something heats up, the speed of the molecules ___________
what is speed up/ increase in speed
400
Feeling the warmth from a campfire.
Radiation
400
What is the Earth's biggest source of radiation?
What is the sun
500
Explain the reason why cold air usually sinks to the bottom and warm air rises up?
What is cold air more dense than warm air, therefore sinks to the bottom
500
What is an insulator?
An insulator stops energy from either entering or leaving an object
500
Explain why it’s much colder at the bottom of a pool than at the top.
Convection makes the cool water sink and the hot water rise.
500
What is a Conductor?
Is an object that lets heat/electricity pass through easily
