REQUIZ Heat Transfer Quiz

What is the process of heat transfer through direct contact between particles of a substance?

• evaporation

• radiation

• conduction

• condensation

Which of the following materials is a good conductor of heat: wood, metal, or plastic?

• metal

• plastic

• rubber

• wood

How does convection occur in a pot of boiling water?

• The water at the bottom becomes denser and rises, while the water at the top becomes less dense and sinks, creating a circular motion of water.

• The water at the bottom becomes less dense and sinks, while the water at the top becomes denser and rises, creating a linear motion of water.

• The heated water near the bottom becomes less dense and rises, while the cooler water near the top becomes denser and sinks, creating a circular motion of water.

• The water at the bottom becomes denser and sinks, while the water at the top becomes less dense and rises, creating a circular motion of water.
