As a part of a science class, a clear pot of water with heat censors is placed above a burner. The

container seems to move upward and the cooler water continuously moves in to take its place
as illustrated below. Which of the following best explains this cyclical movement of the water? -
✔✔✔-Heat is convected through the water, causing the hotter, less dense water to rise. Cooler,
denser water then moves in to take its place.
