What is the definition of a conductor?
Something that conducts (absorbs) heat well
100
What is the definition of an insulator?
Something that does not conduct (absorb) heat very well
100
Does heat rise or sink?
Heat rises because it becomes less dense
100
Does cold air rise or sink?
Cold sinks, because heat rises, and cold moves to replace it.

Give one unit that temperature can be measured in
kelvin, celsius, fahrenheit

Warm clothes prevent you from losing radiant heat. Are they insulators or conductors
insulators
200
Are frying pans good conductors or good insulators?
Frying pans are good conductors
200
Do the molecules in a cube of ice move or are they completely still?
They still move a little.
200
Is copper a conductor or insulator
conductor
300
Are Styrofoam coffee cups insulators or conductors?
insulators. They don't conduct heat.
300
Is a log of wood a conductor or an insulator?
It is an insulator.
300
The circular pattern created by the process of convection is called
convection current
300
What method of heat transfer is this?
Conduction (energy transfer via contact)
300
At what temperature does water boil in degrees celsius
100
400
Is mercury an insulator or conductor
conductor

in the diagram below, what will happen to the pin, which is stuck to the wire with wax?
the metal wire is a conductor, so it will heat up, melting the wax and causing the pin to drop.
400
What method of energy transfer is this:
Conduction (energy transfer via contact)

Explain why the rug on your floor feels warmer than the tile in the same room. Use the terms insulator and conductor
the rug is an insulator, so does not conduct heat from your feet. The tiles are conductors, and will absorb the heat from your feet, making them feel cold.
500
Use your knowledge of particle theory and heat transfer to explain which spoon should you use from the diagram below:
the metal spoon with the wooden handle. Metal is a conductor and will heat up as the particles gain heat energy. The wooden handle is an insulator and will not.
500
What method of heat transfer is shown here:
Convection heating (movement of fluids between regions of different temperature)
500
define temperature
measure of how hot or cold something is

Imagine you are holding a metal bar in one hand, and a piece of wood in the other. Which one will feel colder, and why? 
wood is an insulator, so is not absorbing the heat from your hand. Metal is a conductor, so is absorbing the heat from your hand, making it feel cold.
600
You have two metal containers, one of which is painted black. They are filled with water and placed near a heater. Which will heat up faster, and why?
The black container will heat up faster, because the shiny can is reflective, and will reflect some heat. So it is less conductive.

What type of heat transfer is used in a microwave
radiation.
