Here's a breakdown:
* Radiation: Heat transfer through electromagnetic waves, like infrared radiation. This is how the sun warms the Earth, and how a toaster oven heats your bread.
* Conduction: Heat transfer through direct contact between molecules. This is how a metal spoon heats up when it's placed in hot soup.
* Convection: Heat transfer through the movement of fluids (liquids or gases). This is how a boiling pot of water heats up, with hotter water rising and cooler water sinking.
Radiation is unique because it doesn't require a medium (like air or water) for heat transfer. It can travel through a vacuum, like the space between the sun and the Earth.
