Thermal Energy Transfer Unit Test Review

Put the temperatures in order according to the average kinetic energy of their particles.

• 67ºF

• Highest average kinetic energy

• 0ºF

• Second-highest average kinetic energy

• 85ºF

• Second-lowest average kinetic energy

• -12ºF

• Lowest average kinetic energy

Match and complete the definitions below.

• Circulating currents of

  fluid or air

• Conduction is best described as heat being transferred through

• Physical contact with

  each other

• Convection is best described as heat being transferred through

• Empty or open space

• Radiation is best described as heat being transferred through

Which observation correctly identifies convection?

• The warm wax rises and cool wax sinks in the bottle.

• I can feel the heat from bottle when my hands are near it.

• The hand gets hot when I touch the bottom of the lamp.

• The lamp heats the bottle when it is turned on.

How would having gloves on change how the heat was transferred when touching the lamp?

• They slow heat transfer by radiation from the glass bottle to the student’s hands.

• They slow heat transfer by convection from the glass bottle to the student’s hands.

• They slow heat transfer by conduction from the glass bottle to the student’s hands.

• They slow heat transfer by convection from the safety gloves to the student’s hands
