fluid A continuous, amorphous substance whose molecules move freely past one another and that has the tendency to assume the shape of its container; a liquid or gas. http://www.thefreedictionary.com
Radiation (emit; flow forward) Electromagnetic waves that directly transport ENERGY through space. Sunlight is a form of radiation that is radiated through space to our planet without the aid of fluids or solids.
How does your body feel when you are standing in the shade? Why? What do you feel when you move and stand in a sunny area? Why? Radiation
Conduction (Heat Transfer Via An Object) Conduction is the transfer of energy through matter from particle to particle Conduction is most effective in solids-but it can happen in fluids. Think about a metal spoon in a cup of hot soup…What happens to the spoon? How is the temperature different if the spoon was resting on wooden kitchen table?
Convection (Heat Transfer Via Movement) Convection is the transfer of heat by the actual movement of the warmed matter. Convection is the transfer of heat energy in a gas or liquid by movement of currents. – It can also happen is some solids, like sand.
