Thermal Physics

Warm air rises and the cool air sinks demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
• Insolation 

The heat from a hot burner to a pot is transferred by ______.

• convection
• insulation
• radiation
• conduction

The sun warming your skin is an example of heat transfer through 

• conduction
• convection
• radiation
• thermal electricity

Radiation is a method of thermal energy transfer that moves -

• through empty space.
• when objects touch.
• only through solids.
• in the motion of fluids.

Which example below is an example of radiation?

• Standing on a hot metal bridge
• The attic is warmer than the basement
• The Sun heating the Earth
• Touching hot sand with your feet

This is an example of a(n)

• Conductor of heat
• Insulator of heat
• Insulator of electrical
• None of the above

What happens to particles as they heat up?

• They slow down
• Nothing
• They don't move
• They speed up

What type of material makes the best insulators?

• Aluminum
• Copper
• Styrofoam
• Metal

What materials would be good insulators for a handle on a pan or pot that would be used on the stove?

• wood or plastic
• metal or rubber
• wood or rubber
• copper or steel

Conduction can only occur between two objects when –

• one object is less dense than the other.
• both objects are in physical contact with each other.
• one of the objects is made of a metal.
• both objects are exactly the same temperature.
