heat transfer

When you heat a pot on a stove, the handle gets warm. Which type of heat transfer is responsible?

• Conduction

• Radiation

• Convection

• All of the above

Convection currents occur:

• Only in liquids

• When a dense substance is warmer than a less dense substance

• In both liquids and gases

• Weakly in solids

Hot water rises and cold water sinks. Is this:

• Convection

• Conduction

• Radiation

Stir frying vegetables is an example of

• Convection

• Conduction

• Radiation

A hot air balloon rises because of

• Convection

• Conduction

• Radiation

You feel the heat from a campfire

• Convection

• Conduction

• Radiation

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

• Conduction

• Radiation

• Convection

• Density

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

• conduction

• convection

• radiation

• Insolation 

What happens when ice cubes melt in a glass?

• Heat travels from the ice to the warmer water.

• No energy is transferred.

• Heat is transferred from the warmer water to the ice cubes.

• The water warms up due to the humidity

Transfer of thermal energy through "space"

• conduction

• convection

• radiation
