Solution
The statement that best describes how a convection current forms in the experiment is: "The Bunsen burner heats the water, which expands, becomes less dense and rises up the tube. The cooler, more dense water is sucked around to be heated in a convection current."
Here's why:
-
The Bunsen burner heats the water: The heat from the Bunsen burner is transferred to the water, increasing the energy of the water particles.
-
The water expands and becomes less dense: As the water particles gain energy, they start moving faster and spread out, causing the water to expand. This expansion decreases the density of the water.
-
The less dense water rises up the tube: Because the heated water is less dense than the cooler water, it rises to the top.
-
The cooler, more dense water is sucked around to be heated in a convection current: As the heated water rises, it displaces the cooler water, which moves down to replace the rising warm water. This movement of water creates a convection current. The cooler water then gets heated by the Bunsen burner, and the cycle continues.
