a lighter or or burner.
The sun heats us by the method of Solar Radiation.
tempareture ,nature of the substance and the controller of the bunsen burner
The core or outer core heats the convection currrents, and therefore is like a stove burner.
I depends on what you class as late but maybe a Bunsen Burner
radiation
This would demonstrate the convection currents that form as the water heats. The water near the bottom of the container will heat up because it is closer to the burner. Warmer water is less dense, so it rises to the top of the container, and the cooler, more dense water sinks to the bottom to be heated. As the water moves in the currents, the confetti will also move up and down, showing exactly how the water is moving.
Conduction through the pan mostly, but also convection as the air around the egg in the pan heats.
The Sun heats plants, animals eat plants, and we eat the animals.
