Both aluminum and iron have densities higher than that of water and ordinarily would sink; if the can was empty and thus (like a boat) able to displace more mass in water (by virtue of its volume) than its own weight, it could then float. However, if it was filled with water, its overall density considering both the metal and the container's content, would be higher than water, and it would sink.
What else can I help you with?
Which one of these are most likely to float on water is it a lead bar an iron nail or aluminum?
Aluminum.
Does aluminum powder float or sink?
Aluminum powder will sink in water because it is denser than water.
Do aluminum blocks float?
Depends on what they're dropped into. Water - no. But drop them into something that's denser than aluminium and they will float.
How can aluminum float on water?
Shape the aluminum to look like a boat, so it displaces enough water to float. The force supporting the aluminum is the buoyant force. It is equal to the weight of the volume of water displaced.
How do you make an iron float?
the modern iron has a small "shell" to hold the water in it now if its empty and is in water it may float from the air inside the iron
Does aluminum powder float in salt water?
Yes
Does a lump of iron float?
Solid iron will float in liquid Mercury. In most liquids it will sink.
Will iron pyrite float?
No, a lump of iron pyrite will sink in water.
Can aluminium float in water?
A solid bar of aluminum would not float, since its density (almost 3 grams per cc) is greater than that of water (1 gram per cubic centimeter). For an object to float in water, its density would have to be less than 1.0.
Can you make aluminum float in water?
Yes, aluminum can float in water because its density is lower than that of water. However, the surface of aluminum quickly oxidizes upon contact with water, which creates a thin layer that prevents it from sinking immediately.
Does the element Iron float or sink in water?
Iron sinks in water because it is denser than water. The density of iron is about 7.87 g/cm^3, while the density of water is 1 g/cm^3. This difference in density causes iron to sink when placed in water.
What makes iron ships float?
The structure of an iron ship is such that its density is less than that of water. Anything with a density less than water will float in water.
