Electromagnetic radiation
Conduction is the process that transfers thermal energy from the heating element to the bread in a toaster. The heating element gets hot and transfers heat directly to the bread through physical contact, causing the bread to toast.
A burning candle transfers energy primarily in the form of heat and light. The chemical energy stored in the candle wax is converted to heat and light energy through the process of combustion.
Thermal energy is primarily transferred in gases or liquids through the process of convection. In convection, heated molecules become less dense and rise, while cooler molecules sink, creating a circular motion that transfers heat energy throughout the substance.
The process that transfers the Sun's energy from particle to particle is called radiation. In this process, energy is transferred in the form of electromagnetic waves, such as light and heat, which travel through the vacuum of space and are absorbed by particles in the Sun's atmosphere and eventually reach Earth.
Conduction is the main process that transfers thermal energy through the metal saucepan. Heat is transferred from the heat source to the metal pan through direct contact of particles within the material.

The process that transfers the Sun's energy the rest of the way to the Sun's surface is called radiation. Energy generated in the Sun's core through nuclear fusion moves outward towards the surface primarily through radiation. Photons generated in the core bounce around, gradually making their way outwards in a process that can take thousands of years before reaching the surface and being released as sunlight.
