It demonstrates that aluminum is malleable.
The physical property that can render tungsten suitable for making filament of tungsten light bulbs is incandescence.
melting point
Floating is a physical property, and is not a 'change' in any sense.
The blending of steel (making alloys) is a physical process. Though the structure of the steel changes, it is still chemically unaltered.
Aluminium is now cheap, easily machined, has a low density and is resistant to corrosion.
Making glue is a chemical process.
The physical property that can render tungsten suitable for making filament of tungsten light bulbs is incandescence.
The manufacturing process by which aluminum foil is made is a classic example of the malleability of metal. Malleability is the property of a metal that allows it to be worked or formed without it cracking. And aluminum is superb in this light. Aluminum foil is made from a big block of refined (pretty pure) aluminum, and this sucker is big. Hey, follow the link to the TechEBlog and watch the short video! It's got it all! From melting refined aluminum "pigs" to getting a big (big!) block of aluminum to rolling it out! Well worth the time and the (little) effort!

No. It is a chemical change.

Chemical. Something else is created as a result, and the composition does change, making it a chemical change.

Aluminum is recyclable by humans but not renewable in the sense of making it. We acquire aluminum by mining and smelting ore containing aluminum.
