Convection Conduction and 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

Which will most likely occur when raw egg is placed on black pavement on a hot, summer day?

• The pavement will conduct the heat and cook the egg.
• The egg will reflect the heat and make the pavement hotter underneath.
• The egg will absorb the heat  and leave the pavement hotter underneath.
• The pavement will absorb the heat from the egg, and the egg will stay raw.

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.

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

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.

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.

Walking on the warm sand sand with your bare feet demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
