Crushing.
Crumpling aluminum foil into a ball would not change the mass of the foil, as the amount of material remains the same. However, the volume would decrease as the foil is compressed into a smaller shape, leading to a higher density due to the same mass being packed into a smaller space. The weight of the foil would remain the same regardless of its shape.
Oh, dude, it's all about density, man. The aluminum ball sinks because it's more dense than water, like a lead balloon at a party. The foil floats because it's less dense, kind of like that one friend who always manages to stay afloat in any situation. So, it's basically science doing its thing, you know, making sure things don't get too boring.
Foil balls usually sink in water because aluminum foil is denser than water, causing it to displace less water than its own weight, resulting in a net downward force. Additionally, the shape of the foil ball may not provide enough buoyancy to keep it afloat.
Thickness is a physical property without any relation with chemical composition or chemical changes.
Alpha particles can be stopped by a piece of metal foil due to their relatively low penetration power. This is because alpha particles have a large mass and charge, making them more likely to collide with the atoms in the metal foil and be absorbed.
Physical. It's still aluminum foil.
Tearing a piece of tin foil is a physical change because the substance's chemical composition remains the same before and after tearing. The appearance and physical structure of the tin foil may change, but no new substances are formed during the tearing process.
Foil cut into pieces represents a physical change.
Cutting aluminum foil in half is a physical change. A physical change alters the form of a substance without changing its chemical composition. In this case, the aluminum foil remains aluminum foil after being cut in half, just in two smaller pieces. No new substances are formed during this process, so it is considered a physical change.
Physical. It's still aluminum foil.

physical change, because you are changing the physical property of the object. you are causing the change by hammering it. If you were to put some kind of chemical on it and it changed the physical property of the object that would be a chemical change.
When aluminum foil is added to copper chloride solution, a chemical reaction occurs where the aluminum replaces the copper in the compound to form aluminum chloride and copper metal. This is a chemical change because the composition of the substances is altered. The physical change that occurs is the color change of the solution from blue to greenish-brown due to the formation of copper metal.
Making aluminum foil demonstrates the physical property of malleability, which is the ability of a material to be hammered or rolled into thin sheets without breaking. Aluminum foil is created by rolling aluminum ingots through a series of rollers to achieve the desired thickness.
Hammering gold into a thin foil is a physical process. It involves physically breaking down the gold and flattening it into a thin sheet without any change in its chemical composition. This is in contrast to a chemical process, which would involve altering the gold's chemical structure or composition to create a thin foil.
The tightly crumpled ball of foil has a smaller volume with less air trapped inside, making it denser and likely to sink. The flat piece of foil has a larger surface area and traps more air, increasing its buoyancy and allowing it to float despite being the same mass as the crumpled ball.
The physical property of malleability demonstrates the process of making aluminum foil. Malleability refers to the ability of a material to be deformed or shaped under compressive stress without breaking, allowing aluminum to be rolled into thin sheets. This property enables the aluminum to be transformed into flexible foil that can be easily shaped for various applications.
