Convection Currents in Fluids: How Heat Transfer Works #3272012 (License: Personal Use)

This diagram depicts thermal convection in a beaker of water heated by a Bunsen burner beneath it. Red arrows indicate warmer, less dense water rising, while blue arrows show cooler, denser water sinking, establishing two convection cells. The process demonstrates how heat energy is transferred through fluid motion without external stirring.

Used in educational science content (e.g., middle/high school physics or earth science lessons) to explain heat transfer mechanisms; matches user intent seeking visual aids for understanding convection, weather systems, or ocean currents.
