The aluminum ball sinks because it has a higher density compared to water, causing it to displace water and sink. The piece of aluminum foil floats because it is thin and has a lot of air trapped in its structure, making it less dense than water and enabling it to float.

Why does the same piece of foil float or sink?
The same piece of foil can float or sink depending on its shape and how it is positioned in the water. If the foil is shaped to trap air, it will float. If the foil is crumpled or folded so it doesn't trap air, it will sink.
Does a crumpled piece of aluminum foil into a ball would the mass weight volume and density increase or decrease from what it was?
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.
Does aluminum sink or float in water and why?
Generally speaking, a denser substance will sink in a less dense substance. Assuming standard temperatures, since aluminum has a density of about 2.7 grams per cubic centimeter and water only has 1 gram per cc, aluminum would sink. A thin aluminum foil could float by virtue of the surface tension on water (but if submerged, will sink). An aluminum boat would float because it displaces a greater mass of water than its own weight. An aluminum block could also float on a liquid of higher density than the aluminum.
How does a tin foil raft float?
A tin foil raft floats due to the principle of buoyancy. The air trapped within the foil pockets increases the overall volume of the raft, making it less dense than water. This causes the raft to displace an amount of water equal to its weight, allowing it to float on the surface.
How does aluminum foil boat float?
Aluminum foil boats float due to the principle of buoyancy. When the boat is placed in water, the upward force of buoyancy is greater than the weight of the boat, allowing it to stay afloat. The shape of the boat helps displace enough water to create this upward force.
Can you make a piece of aluminum foil float in air?
No, aluminum foil is denser than air so it will not float on its own. It would require a strong updraft or force, such as being propelled by a fan or other means, to keep it suspended in the air.
Why might a tightly crumpled ball of foil sink but a flat piece of foil of the same mass float in water?
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.
How can aluminum foil float in water?
Aluminum foil can float on water due to its low density, which allows it to displace a greater amount of water than its own weight. This creates buoyant force that keeps the foil afloat.
What Explain why you can see your reflection more clearly in a piece of aluminum foil than in a piece of white paper.?
The aluminum foil is smoother.
What are physical properties of a piece of aluminum foil?
A piece of aluminum foil has a fixed mass and volume, it is flexible, and it is a metal that can conduct electricity.
Why does the same piece of foil float or sink?
The same piece of foil can float or sink depending on its shape and how it is positioned in the water. If the foil is shaped to trap air, it will float. If the foil is crumpled or folded so it doesn't trap air, it will sink.
What are 4 physical properties of a piece of aluminum foil?
Malleable, brittle, ductile
Why do boat made from aluminum foil float in xenon gas?
it floats because the xenon gas particles are heavier that the aluminum foil's.
How thick is a piece of aluminum foil in millimeter?
Standard aluminum foil is typically around 0.016 mm thick.
What is the reason that a crushed tin ball of foil will sink and and flat piece of it floats?
A flat piece of tin foil may float on top of water due to surface tension. A crushed ball of foil does not have near the amount of surface area in contact with the surface of the water, so the surface tension is not sufficient to keep it suspended. Note that if you place a flat sheet of foil in the bottom of a container and pour water in on top of it however, it will not rise to the top to float; you have to place it on top carefully in order to get it to float.
What happens when you fold aluminum foil to small piece?
When you fold aluminum foil into a small piece, it can be used to charge a dead battery. The electrical charge is present when it is folded up.
What would be the reaction when a small piece of aluminum foil reacts with sulfuric acid?
When a small piece of aluminum foil reacts with sulfuric acid, it will produce hydrogen gas and aluminum sulfate as products. The reaction is exothermic, so heat may be observed. Additionally, the aluminum foil will dissolve as it reacts with the sulfuric acid.
