If you put a piece of aluminium foil in the fridge freezer?

If you put a piece of aluminium foil in the fridge freezer, do the molecules constrict and the foil become lighter in weight ?

1. NO
2. Put it in the microwave {0_o}
3. Of course it doesn't. The mass remains the same. The only thing that happens is it drops to the same temperature as it's surroundings!
4. Mass will remain the same..the Aluminium will contract in volume so density=Mass/volume will increase.
5. Oh, so do you imagine very hot vapourised aluminium is heavier than solid aluminium? I use aluminium vapour to coat mirrors for telescopes. I'm glad it acts as a normal vapour. When things contract through cooling, the mass stays the same but the volume decreases so the density increases. Not by much, and for water it's reversed. Water acts funny that way. It's got 9/10ths of it's density as ice than as water which is why ice floats.
6. Yes. Molten metals have no structure. The atoms inside are moving around randomly, very quickly.But Solid state metals have nuclei particles inside which are like crystals with meeting points called grain boundries. Thin foil structures normally produce body-centered fixed hexagonal formations inside after cooling, which are susceptible to loss of mass in very cold conditions. They compress and mass is lost as protons fuse.This is why when you put a Kit Kat wrapper in the fridge, it will literally half in size when you finally remove it. The loss off mass can be explained with this brief equation: FCC = a(x)=ao 1800 (tce -ted)/L2 }X2 +tce !/tce !(-1/p) (The apparatus of claim 8, wherein (L)/(tce) is greater than 1786).
