Here's how it works:
* Liquids and gases: These substances have molecules that are able to move around freely.
* Heating: When you heat a liquid or gas, the molecules at the bottom absorb energy and move faster.
* Rising: These faster-moving, warmer molecules become less dense and rise.
* Cooler molecules sink: As the warm molecules rise, cooler, denser molecules sink down to take their place.
* Continuous cycle: This creates a continuous cycle of rising warm molecules and sinking cool molecules, transferring heat throughout the liquid or gas.
