Objects denser than water will sink; objects less dense than water will float. Since aluminum metal has a density of around 2.7 grams per cubic centimeter and water has a density of 1.0, a solid block of aluminum would sink.

How can you use the density of an object to predict whether it will sink or float?
First, what will the object be floating on? The principal to your question is: for an object to float, its density must be equal to or less than the density of the liquid on which it is to float. A brick will float on top of mercury, because mercury is more dense than the brick. A cork will float on water because the cork is less dense than water. The same works for gases. An aluminum baking pan will float on the invisible gas sulfurhexaflouride because SF6 gas is more dense than the baking pan.
Can lead weights sink or float?
It depends upon its shape. A solid brick of lead will sink. A lead weight pressed into the shape of a bowl will float, because it displaces more water, and is therefore buoyant enough to float.
When a brick is lowered into a bucket full of water some of the water spills out over the sides why does it happen?
Why it happens because the mass of the brick is heavy and the force apon it is because of its weight and it makes it float and spills out of the bucket.
What affects the ability of an object to float on a fluid?
Its density compared to the density of the fluid.It is based on the buoyancy of the object. This is affected by the amount of matter of the object per a certain area as opposed to the fliud. One example is the igneous rock pumice. As opposed to obsidian, another igneous rock, it floats on water. Its buoyancy allows it to float on water (one of the very few rocks that can float on water). So, it is based on the buoyancy, or the amount of matter in a certain area as opposed to the same amount of the liquid. the lighter and less dense the amount, the more it will float. If its density is high, it will sink, while a low density object will be more likely to float. (For example, a small foam block versus a brick of the same size. They take up the same amount of space and can be compared. The foam block floats due to its low density. Meanwhile the brick sinks because it is very dense.) so, in a short answer, buoyance, or the ability to float, is based on the density of an object.
What must be equal for a ship or boat float?
The Archimedean Principle; 'The weight of a body immersed in a fluid is equal to the weight of the fluid displaced'. I learnt that at school aged 11 years. For a ship/boat to float, the weight of the metal may be 'x' tons, but it will displace an amount of water of 'x+y' tons, so it will float. If there is a hole in the ship/boat that allows water in to fill the internal space of the ship/boat, then it will sink ,because the weight is now 'x-y' tons. As an experiment for your self. Find the weight/mass of an house brick, say 3 kgs. Attach it to the end of a spring balance, so you can see the weight. Then slowly lower the brick still attached to the spring balance, into a tank of water. The weight of the brick may now be only 1 kg. The difference is 3kg - 1 kg = 2 kg which is the weight of the water displaced.
How much salt does it take to make a brick float on water?
for a brick to float on water 2 thirds of the mixture should be salt
What Solids that don't float on water?
one answer is a brick.A brick does not float on water.
Can you give me a sentence using the word float?
The aqua blue toy sailboats float on the tranquil pond unlike the heavy red brick.

What items will float in water Canoe Flower Petal Brick or A Rollar Skate?
Probably a rollar skate. (Not sure. :-|)
How can an whale of 600 lbs float and a brick dont?
Well, whales have special physical attributes that help them keep afloat. for example, it has a special liver filled with oil that helps it to swim. it also uses movement and its fins to keep from sinking. we weigh a tad more than a brick and we still float because we have special adaptations that stop us from sinking - we can swim! can a brick swim? does a brick have these special physical attributes? no! we are alive - bricks aren't.
What principle is it when a brick doesn't float on water?
Archimedes' Principle. It all depends on the buoyant force and the densities of the two objects.
When a brick is lowered into a bucket full of water some of the water spills out over the sides why does it happen?
Why it happens because the mass of the brick is heavy and the force apon it is because of its weight and it makes it float and spills out of the bucket.
What happens to brick when its melted?
If you get brick hot enough to melt, it would change into silicon Any impurities with a different melting point would burn off or float on the silicon and when allowed to cool the silicon would resemble obsidian.
Does cloth float in water?
The cloth swells as the water enters and occupies the empty spaces amongst the cloth's fibres.
