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.
What else can I help you with?
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.
Does aluminum powder float or sink?
Aluminum powder will sink in water because it is denser than water.
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.
Will a lump of aluminum sink or float?
Sink
Does aluminum powder float in salt water?
Yes
Why does a aluminum can float?
the air inside the can keeps it afloat
Which one of these are most likely to float on water is it a lead bar an iron nail or aluminum?
Aluminum.
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.
Do aluminum can peices sink or float?
Answer #1: float.==========================Answer #2:The density of aluminum is 2.7 gm/cm3.So, just like steel, if you shape a piece of it just right so that it displacesenough water, you can make it float. But a lump of it will sink in water.
Does aluminum soda cans float in water?
No, aluminum soda cans will sink in water because aluminum is denser than water. The air trapped inside a closed soda can may cause it to briefly float, but it will eventually sink.
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.
Would a block of aluminum float or sink in a pool of mercury at room temperature with a density of 13.6?
A block of aluminum will float on a pool of mercury at nearly any temperature (except at extremely elevated temperatures (above 350 °C) where mercury is no longer liquid) The density of aluminum is 2.70 grams per cm3, whereas the density of mercury is 13.53 grams per cm3. Therefore mercury is more than 5 time more dense than aluminum! Anything that is less dense than a liquid will float in that liquid. Not only would aluminum float but it float with only 1/5 of it's volume submerged.
