How is the density of a floating object relate to the density of the fluid it is floating in?

If an item floats, Then it is less dense than the liquid it floats in. One can prove this using bernoulli's equation. To determine the weight of the floating object, take the volume of water displaced by the portion of the object below the fliud surface then multiply that by the density of the fluid. This process gives you the bouyant force on the floating object and therefore the weight. Then take that weight and divide it by the total volume of the. Object to get its density. Also note that if an item is suspended below the surface but. Above the bottom of the fluid body, then the item and fluid have equal density. If the item sinks to the bottom it has higher density than the fluid.


What is the tendency of an object to float?

Whether a material in any state of matter (solid, liquid or gas) will float in a liquid (or a gas) depends on the relative densities of the materials. (Density is defined as mass divided by volume.) If the density of the object is less than the density of the liquid it is placed in, the object will float. If the density of the object is greater than the density of the liquid, the object will sink. If the densities are the same, the object will remain stationary assuming there are no other forces acting on it. For a few examples, a plank of wood is (generally) less dense than water, so it would float. A balloon filled with Helium is less dense than air, so it rises. A ball of lead is more dense than water, so it sinks. You can even float a liquid on top of another liquid if their densities are different.


How do you calculate find the density of an object that floats?

If you can determine the volume fractions of the object that are above and below the water, then you can find the density of the object by multiplying the density of the fluid it floats in by the fraction of the volume that is below the surface of the liquid. Another, more complex way is to weigh the object alone then attach it to one arm of a balance to weigh the object when it is floating. As it floats it will displace an amount of liquid equal in weight to the total object. The decrease in weight will be proportional to the fraction of the object that is submerged. As an example: If an object weighed 100 grams out in the air but only required 20 grams to counterbalance its weight when it is floating, and the fluid it was floating in was water, then the density of the object would be (1 g/cubic centimeter)·(100-20)/100 = 0.8 g/cubic centimeter.


If 90 percent of an object is floating below water what is its density?

Let's say the object has mass M and volume V. An object floats by displacing an amount of water equal to the object's mass. So water equal to 90% of the volume of the object has mass equal to the whole object, or M = 0.9V * 1g/ml or M = 0.9V Since density is mass divided by volume, or d = M/V, density of object = M/V = 0.9 g/ml.


As matter is heated what happens to the density of the matter?

In general, a solid object will expand when heated. That means that it's volume increases, but because the object's mass (weight) does not increase, the density is reduced. the equation is Mass/Volume.Like many rules however water (as ice) does not follow this exactly. Ice expands slightly as it cools below 70 K

Water has a density of exactly 1. Anything below 1 will floatin water.


What happens to the density of air as you go further below sea level altitude but in dry land?

Density always increases as altitude decreases. So the air density below sea level will be greater than the air density at sea level.

What happens to an object when it is placed in a less dense liquid or gas?

The density of the object goes through the less denser liquids until it gets to a liquid that is more dense than it. The first liquid that is denser than the object, the object will float on the liquid. My class did this in Science Class.

Does the object float or sink the higher the density?

The the object you speak of is in water at approximately room temperature, then anything with a density above about 1 will sink; anything below 1 will float and anything at very close will be suspended in the water. So, to answer your question, high density equals sinking.

Why do things float if there is more density in the water?

If the density of the unknown is more than the density of water , it will sink If the density of the unknown is less than the density of water, it will float. Things do not float unless their densities are below that of water which is 1.00 g/ml.


How does the density of an object that sinks into a fluid compare to the density of the fluid?

Oh boy. Density is the mass per volume...grams per cubic centimeter, tons per cubic yard, whatever. Water's density is one gram per cubic centimeter. An object with lower density than water will sink into water until the number of cubic centimeters corresponding to the mass of the object are below the surface of the water. If the object is 100 cubic centimeters and it weighs 50 grams, half of it will be below the surface and half above. This is buoyancy, or "floating." Cool so far? If an object's density is more than one gram per cubic centimeter, the whole thing will be below the surface of the water. Because the water can't support the weight of the item, it will sink to the bottom given enough time. If it sinks, its density is greater than water...but without weighing it, we can't say how much greater because an item with mass of 5 grams and density of 1.1 grams per cc will sink as surely as a 300-pound anvil with density of 7.2 grams per cc. It just won't do it quite as fast.
