Aluminium is 2.7 times denser than water. When in water it will sink below the surface, being more dense.
Another way to look at the problem is to say that the aluminum, on displacing its own volume of water, will receive upthrust equal to the weight of water displaced and will thus seem lighter. As the upthrust will be less than the weight of the block, it will not be sufficient to cause the block to float.

Which will float on water a 1-kg block of wood or a 1-kg block of aluminum?
Wood will. A solid block of aluminum will sink. Things float when their density is less than water. There are some woods that sink.
Which will float in water a 1kg of block of wood or a 1 g block og Aluminum?
In most cases the wood will float (there are a few dense tropical woods that will not) and the metal will sink. things float because they displace more weight of water than their own volume if not they sink
Would a block with holes in it sink in water?
Depends on what the block is made of. A block of wood will float. A block of concrete will sink.
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.

Why will a crumpled ball of aluminum sink in water?
Yes
How many pennies does it take to sink the aluminum size 10 centimeters?
The question depends on what the aluminium is floating in. It is denser than water so will sink a block will sink in water without any pennies. If, on the other hand, it is shaped (like a boat) then the number of pennies required will depend on the shape.
If a block of ice has the density of 0.97gcm3 how much of it will sink below the water?
97% will sink below the water
Will a block of aluminum sink or float in a pool of mercury?
i aslo got this answere supported by my teachers and my advanced science ; science book. word for word. p.s. thank all of you other users for posting you comets ect...
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.
Will aluminum pellets float in water?
Not if the pellets are solid. Aluminum will sink in water because its density (2.7g per cc) is greater than water (1.0g per cc).
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.
