Heat Transfer

What kind of heat transfer happens when the sun heats your body?

• Conduction
• Radiation
• Convection
• Density

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

• conduction
• convection
• radiation
• Insolation 

When you iron a shirt, the shirt gets warm.  This type of heat transfer is an example of

• condensation
• conduction
• convection
• radiation

Warm air is __________ dense than cold air and rises creating convection currents.

• more
• less

The man takes the hot pot off the stove with his bare hands and his hands get burned.  This is an example of 

• conduction
• convection
• radiation

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

A group of friends gather around a fire to stay warm.  This is an example of

• conduction
• convection
• radiation

The baby chickens are kept warm from the heat lamps. This demonstrates what kind of heat transfer? 

• conduction
• convection
• radiation

The transfer of heat by currents through liquids of gases is called

• Perspiration
• Radiation
• Conduction
• Convection

A metal spoon heated by hot soup.  This is an example of

• Conduction
• Transpiration
• Convection
• Radiation
