Does a crumpled piece of aluminum foil into a ball would the mass weight volume and density increase or decrease from what it was?
All that has changed is the 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, which is just a flat piece of tin foil (which we know is really aluminum foil), floats by means of the surface tension of the water that supports it. We all know that aluminum is more dense than water. A block or other chunk of aluminum would sink in water. But because the aluminum foil is thin, its mass is "spread out" over a wide area, and this causes a broad interaction with the surface tension characteristic of water.

How does aluminum foil boat float?
An aluminum foil boat floats because it is more dense than water, therefore the surface tension of the water is able to hold the boat up.
Is aluminum foil a better heat conductor than metal?
no because aluminum foil is a metal
Can you make a piece of aluminum foil float in air?
yes
How can aluminum foil float in water?
A thin aluminum foil can float on water if placed carefully flat on the surface because of the surface tension of water. If you were to submerge it, the foil will sink.
Why might a tightly crumpled ball of foil sink but a flat piece of foil of the same mass float in water?
A tightly crumpled ball of foil might sink in water because it's density is greater than water. When foil is flat it's density is less than water and it will float.
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.
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.
Does a crumpled piece of aluminum foil into a ball would the mass weight volume and density increase or decrease from what it was?
All that has changed is the shape.
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.
