Answer 1

The correct answer is **Convection**.Here's why:* **Convection** is the transfer of heat through the movement of fluids (liquids and gases). In this case, the heated water becomes less dense and rises, while the cooler, denser water sinks. This creates a circular motion called a convection current.* **Conduction** is the transfer of heat through direct contact between molecules. While conduction plays a role in heating the water initially, it doesn't explain the circular motion.* **Radiation** is the transfer of heat through electromagnetic waves. This isn't the primary method of heat transfer within the pot of water.* **Density** is a property of matter, not a method of heat transfer. While density differences *drive* convection, they aren't the heat transfer method itself.
