There are many kinds of energy. Energy is the ability to do work, like move an object. It cannot be created or destroyed. This kind is called thermal energy
This bed is pretty warm...
Man... The sun is blocking this view of the ocean..
This kind of energy is called light energy.
and that brings us to where we are today, the three types of heat transfer. Conduction is when a object heats up through a solid or gas. Convection is when heat rises up from a fluid. And radiation is when heat or light travels in waves in the vacuum of space.
