What boiling on a pot in a kettle is a example of?

Boiling water in a pot on a kettle is an example of heat transfer, specifically convection and conduction. The heat from the kettle is conducted through the pot, raising the temperature of the water inside it. As the water heats up, convection currents form, causing the hotter water to rise and the cooler water to sink, leading to boiling. This process illustrates the principles of thermodynamics in action.
