Define convection by completing the sentence. Convection is heat transfer:

Which of the following statements best describes how a convection current forms in the experiment below?The Bunsen burner heats the water particles and they expand. The less dense water particles rise up the tube. The cooler, more dense water particles are sucked around to be heated in a convection current.The Bunsen burner heats the water, which contracts, becomes less dense and rises up the tube. The cooler, more dense water is sucked around to be heated in a convection current.The Bunsen burner heats the water, which expands, becomes less dense and rises up the tube.
