The process you’re describing is called “convection.”
Example sentence: In a pot of boiling water, convection occurs as the hot water rises to the surface while the cooler water sinks to the bottom, creating a circular motion.
Explanation: Convection is a heat transfer mechanism that happens in liquids and gases. When part of a fluid is heated, it becomes less dense and rises. Cooler, denser fluid then moves in to take its place, causing a movement that transfers heat throughout the fluid.
