Now, I'm doinq my Science Fair ProjectIts about wether the Cookie Sheet a cookie is baked on affects how the cookie turns out.Now, I have to write somethinq about heat transfer and aluminum and parchment paper.I know NOTHING about itI Need help.!!! Major Help.!Im, a 7th qrader, so make your answers understandable please.!But answer quick, its due on the 4th(This Friday.!) 10 Points to the best answer.
Aluminum is usually extruded into shape from ingots at the smelterFinal shaping and trimming is done on a milling machine or a turret lathe.
I believe its called a milling machine.
It`s called a THINGAMABOB or thingy for short.
Heat transfer is energy in transit as the result of a temperature differenceThere are 3 mechanism of heat transfer: 1Conduction, is heat transfer through a solid body2Convection, is heat transfer from a solid surface to a moving fluid3Radiation, is heat transfer/generate due to its own temperatureex: Heat transfer on your wallThe sun generate heat radiation to the earthThe heat transfer between the hot air (outside) and the outer surface of your wall is called convectionThe heat transfer from the outer surface of your wall through the inner surface of your wall is called conductionOn conduction heat transfer, the material has a single properties that affect the heat transfer and that is called thermal conductivity (k)The higher the k value is the better heat transfer occurred and the lower heat resistanceAluminum is consider having high value of thermal conductivity.
