What are three mechanisms of energy transfer?

Answer 1

There are many mechanisms of energy transfer, assuming you simply mean transferring energy to or through something. Here are a few:

1. Radiation as electromagnetic radiation (e.g. UV light from the sun hitting your skin and causing a sunburn transfers electromagnetic energy from the sun to your skin)
2. Physical collisions (e.g. a car hitting a tree and causing it to break transfers kinetic energy from the car to the tree)
3. Thermal conduction (e.g. heat moving from your warm hand to a cold ice cube transfers molecular vibrational energy from your hand to the ice cube)
4. Electrical conduction (e.g. current in a wire transfers electrical energy through a circuit)
5. Thermal convection (e.g. a warm air current rises over a cold one due to its lower density, transferring heat energy from one part of the atmosphere to another)
