if the diameter of the aluminum atom is 0.5 nm, how many atoms are there in a grain of ASTM grain size 5?
This Site Might Help YouRE: Can I put my non-stick frying pan in the oven? I'm cooking and I want to put the stuff in the oven for awhileDo I need to put it in a new pan or can I put the frying pan in the oven? It doesn't have a rubber handle or anything.
Look at the pan specifications, Calphalon has pans that are oven safe 500 degrees and made in USAIf you don't specifically look for the pan that is oven safe you wont knowSeveral of the above answers sound good but are wrongThere are other brands as well that are non stick and oven safe, and they very clearly tell you what the temp limits.
As long as the handle is oven safe, you can put it in the oven, My kitchen aid frying pan says oven save! Wrong!!!!!! Do not and never put your frying pan in the oven even if it says oven safeI does releases a smell that is equivalent to ammonia, bleach heavy smell so I found outThe manufacture should have disclosed the type of toxic gas! after all we use it to cook our food in this is not food safeMy oven temperature was at 300F, I will use stainless steel from now on, it is food safe.
Art is thinking 2 dimensionallyHowever for the correct answer to your question you must think in 3DThe first thing to do is to make a gross assumption as to the shape of an average grainWhile there are numerous thoughts on the subject including complicated polyhedrons we will stick with a sphere because the math is easierDiameter of atom is .5nm and diameter of grain is 64 micronsVolume of grain is 4/33.14R^3 4/33.14(32E-6)^3 1.37E-13 m^3 Volume of atom is 4/33.14(.25E-9)^3 6.55E-29 m^3 simple division gives 2.097E15 atoms per sphereBut not so fast, Aluminum is FCC and therefore has a theoretical packing density of .74 so that there are fewer atomsWith that in mind a closer guess is 1.55 E15 atoms per grain.
