Conduction, Convection, & Radiation

The heat from a lamp allows a lizard to remain warm. This is an example of which type of heat transfer?

• radiation

• conduction

• convection

• insulation

Jordan places a hot spoon into a container of ice cream. How does this help him scoop  out the ice cream? 

• The coolness from the ice cream is conducted to the spoon making it easier to scoop out.

• The coolness from the ice cream is radiated to the spoon making it easier to scoop out.

• The warmth of the spoon is conducted to the ice cream  making it easier to scoop out.

• The warmth of the spoon is radiated  to the ice cream making it easier to scoop out.

Which describes what can happen as a result of radiation?

•  A piece of wood burns in a fire.

• A shirt is hot after having been  ironed.

• A can of soup is heated in a pot on a stove.

• A car’s inside temperature rises  to over 100 degrees on a sunny day.

John put a heat pack on his cold feet. What will most likely be the result?

• The cold from John’s feet will  be radiated into  the heat pack.

• The warmth of the heat pack will be radiated  onto John’s feet.

• The cold from John’s feet will be conducted  into the heat pack.

• The warmth of the heat pack will be conducted  onto John’s feet.

Which best describes the process of convection?

• Convection is the primary way  heat travels  through rays.

• Convection is the primary way heat travels  through metals.

• Convection is the primary way heat travels  through appliances.

• Convection is the primary way heat travels  through liquids and gasses.

How is heat transferred when boiling a pot of water on the stove?

• conduction

• convection

• combustion

• radiation

Which is an example of heat being transferred by conduction?

• a furnace heating the air in a school

• an ice cube melting in a person’s hand

• a pot of water on a stove boiling

• the sun heating water in a swimming pool

What is the definition of CONVECTION

• When heat transfers through waves.

• When heat transfers from objects that are touching.

• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.

• Heat traveling from the sun

Which of the following is an example of convection?

• A hair dryer is drying up your hair.

• When the AC or heater changes the temperature.

• When a car engine turns hot after being turned on.

• When you are making soup and the water is rising and lowering.

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

• conduction

• convection

• radiation

• Insolation
