Is folding aluminum foil a chemical or physical change?

Aluminum foil is a physical change. A further explanation is given below.

Explanation:

The processing of aluminum foil starts with either a succession of cool rolling procedures, wherever another density including its aluminum alloy becomes diminished by half amongst every method.  Aluminum foil modified thickness and weight, but it would be an aluminum sheet, so it would be a physical transition or change.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
