Did you know heat moves in three main ways? Conduction, convection, and radiation. Conduction happens when heat travels through solids—like a spoon warming up in hot soup. Radiation is heat moving through waves, like the warmth you feel from the sun. And convection? That’s when heat moves through liquids or gases, creating currents. Let's take a closer look at convection.
In this first example, as the burner heats the liquid, the warmer, less dense liquid rises, and the cooler, denser liquid sinks, creating a continuous flow—this is a convection current. You’ll see the same principle with this hot air balloon. The burner heats the air inside, making it expand and rise, causing the balloon to lift.
