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?

• Sun light

• frying bacon

• Sea breeze

• Taking a warm shower

Radiation is the transfer of energy by what?

• Which is an example of radiation?

• Roasting a hot dog over a fire.

• A hot air balloon

• Using lotion to soothe a sunburn

• 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?

• Metal

• Copper

• Plastic

• A&B

Which is a poor conductor , but not an insulator?

A. Plastic

B. Metal

C. A cake pan

D. 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?

• Wood

• Ceramic tiles

• Sock

• B&C

Which would not let heat in at all?

Plastic or Ceramic Tiles

True of False

Are insulators always solids?

Why do people put rubber around chargers of computers?
