Heat Transfer

If you put a metal spoon and a wooden spoon into a pot of boiling water, one will become too hot to touch.  Why?

• Metals conduct heat better than wood.
• Wood conducts heat better than metals.
• Metals pull in heat because heat is attracted to metals.
• Wood isn't as strong as metals.

• A black sweater
• A white sweater
• A snowball
• Aluminum foil

Hot air moving up is an example of 

• Radiation
• Conduction
• Magic
• Convection

Poor conductors like wood and plastic are called:

• conductors
• insulators
• burners

Which best describes the flow of heat?

• from a larger object to a smaller object
• from a warmer object to a cooler object
• from a cooler object to a warmer object

In what way does the Sun warm Earth? 

• radiation
• convection
• conduction
• condensation

What conditions are necessary for heat conduction to occur between two objects? 

• The objects must be surrounded by air or water.
• Two objects at different temperatures are touching one another. 
• Two objects at different temperatures are located close to one another. 
• One object must emit energy as light and heat and another object absorbs the energy.
