When Conduction happens is direct or

indirect heat transfer?

When 2 things are touching in conduction

do the have to be different temperatures?

Why?

If you are frying bacon with a metal pan and a metal handle and your hand gets hot where is the heat coming from?

(Name the whole process)

What do you think would happen if you were

cooking with a metal pot and you had a pot holder on your hand when you

touched the hot pan would you get burned?

Why?

True or false?If you touched the inside

of a microwave right after it stopped warming something up it would be

hot?

Convection is the transfer of heat ?

Can convection move through solids or just liquids and gasses?

What’s the difference between conduction and

convection

Convection in the oceans and

atmosphere help to move what around the

earth?

Which of these is an example of convection?

A. Sun lightB. frying baconC. Sea breezeD. Taking a warm shower

Radiation is the transfer of energy by what?

Which is an example of radiation?

A. Roasting a hot dog over a fire.

B. A hot air balloonC. Using lotion to soothe

a sunburnD. Warm air rising

True or false?Electromagnetic waves

can’t carry energy through places with or

without matter?

What is the main source of

electromagnetic energy on earth?

Which is more powerful a microwave a fire place or

a lightbulb?

Which is a good conductor a sock or a

penny? Why?

Which are better conductors?

A. Metal B. Copper C. PlasticD. A&B

Which is a poor conductor , but not an

insulator?A. PlasticB. Metal C. A cake panD. Iron

If you had a frying pan with a metal handle,

would you want to put rubber around it?

Why do people use glass cake pans instead of plastic cake pans?

What is an insulator?

Which is an insulator?A. WoodB. Ceramic tilesC. SockD. B&C

Which would not let heat in at all?

Plastic or Ceramic Tiles

True of FalseAre insulators always

solids?

Why do people put rubber around chargers

of computers?
