Question

jamal is investigating heat transfer through conduction. they decide to use a lava lamp for their investigation. they explain that because there is hot matter rising and cool matter sinking, they are observing conduction. their teacher says their investigation is incorrect. how could you help jamal modify their investigation to observe conduction with a lava lamp?
tell jamal to microwave the lava lamp to observe conduction.
tell jamal to hold the lava lamp over a bunsen burner so the hot air rises and heats the system.
tell jamal to touch the hot lava lamp so it transfers its thermal energy to their hand.
tell jamal to take the lava lamp outside so that the sun can heat it up and create a current.

Explanation:

Conduction is the transfer of heat energy through direct contact. Touching the hot lava - lamp allows heat to transfer from the lamp to the hand through direct contact, which is conduction. Microwaving the lamp is a form of radiation heating, holding it over a Bunsen burner is convection (hot air rising), and taking it outside for the sun to heat it is also radiation.

Answer:

Tell Jamil to touch the hot lava lamp so it transfers its thermal energy to their hand.
