Exploring Heat Transfer: Conduction, Convection, and Radiation

Mrs. Buddhison conducts a heat transfer lab, exploring conduction, convection, and radiation through three experiments. The first uses a lava lamp to demonstrate convection, the second involves aluminum foil and butter to show conduction, and the third uses a radiometer to illustrate radiation. Each experiment is explained with a hypothesis and results, providing a comprehensive understanding of heat transfer types.

What is the first step you should take when starting any lab experiment?

• Gathering materials

• Formulating a hypothesis

• Recording data

• Identifying the question

Which type of heat transfer is being demonstrated with the lava lamp?

• Conduction

• Convection

• Radiation

• None of the above

What causes the wax in the lava lamp to rise to the top?

• It becomes more dense

• It becomes less dense

• It cools down

• It solidifies

In the aluminum foil and butter experiment, what is the primary heat source?

• The stand

• The candle

• The butter

• The aluminum foil

How does the heat transfer to the butter in the aluminum foil experiment?

• Through radiation

• Through convection

• Through conduction

• Through insulation

What is the purpose of folding the aluminum foil in the butter experiment?

• To make it more flexible

• To make it more conductive

• To make it more reflective

• To make it stronger

In the radiometer experiment, what causes the radiometer to spin?

• Magnetic fields

• Convection currents

• Heat waves traveling through space

• Direct contact with the lamp
