A student wishes to conduct an investigation on heat transfer that demonstrates convection. Which method should the student use?

Question

Group of answer choices

Melt chocolate bars in a microwave at different settings.

Leave a glass of ice water outside in the direct sunshine.

Pour hot, colored water into a bowl of cooler water that is another color.

Place a spoon that is room temperature on top of a hot burner on a stove.

Answer 1

To investigate heat transfer that demonstrates convection, the best method for the student to use is:

Pour hot, colored water into a bowl of cooler water that is another color.

This method clearly demonstrates convection currents, as the hot colored water will rise and the cooler water will sink, illustrating the movement of fluids due to differences in temperature and density. The other options either don't primarily demonstrate convection or involve other forms of heat transfer like conduction or radiation.
