What method would you use to separate wood and brick pieces?
Wood float on water, bricks not.
Ships float submarines sink?
Wrong!!!! Ships float, and submarines also float. However, submarines have special buoyancy tanks, which are filled with sea-water, which then makes then sink. The air in these tanks is removed by a vacuum, out into compressed air cylinders. , this allows water to enter and hence the submarine sinks. To make the submarine re-surface, the compressed air in the compression tanks is blown back into the buoyancy tanks, thereby pushing out the sea-water, hence the submarine re-surfaces(floats). Remember the Archimedian Principle. 'The weight of a body immersed in a fluid is equal to the weight of the fluid displaced'. As an experiment to yourself, obtain a spring balance, an house brick and a tanks of water. Attach the brick to the spring balance, with a piece of string, and note the weight in air. Now keeping the brick attached to the spring balance lower it into the water of the water tank, and note the new less weight. The difference in the weight is the weight of the water displaced by the brick. Hence Archimedes principle and the reason why ships and submarines can float, because the displace less water.
Can you put salt in water to make an object float?
If the object does not quite float in water, adding salt to the water might make the object float, yes.
Does a rubber band float?
Yes and no. Rubber bands can float and sink in water. They will float on the water for awhile and then will sink. But not all the time the rubber bands will float on the water for awhile. Sometimes it will immediately sink.
Does kerosene float on water-?
no, beacuse there is more sugars patick present in it so it floats
What Solids that don't float on water?
one answer is a brick.A brick does not float on water.
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
How would you determine the density of 10 grams of granular zinc?
using water displacement because it doesnt float on water and it doesnt dissolve in water
What is a boat that can float on water?
wow that's sad a boat that can float is any tye of boat that doesnt have a hole in it
What method would you use to separate wood and brick pieces?
Wood float on water, bricks not.
Does sugar cubes float in water?
no it doesnt because it has lots of mass which makes in sink.

What items will float in water Canoe Flower Petal Brick or A Rollar Skate?
Probably a rollar skate. (Not sure. :-|)
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.
An object less dense than water will in water?
The "average" density of the object must be less than that of the water displaced.
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.
