The higher the density, the lower the buoyancy and the lower the density, the higher the buoyancy

Higher the difference of water density to object density is higher buoyancy force.

Buoyancy is the factor of things that float or sink. Density is related because if the object has more density than water, it will sink. But, if it has less density than water, the object will float.

If the average density of an object is less than water (1.0 g per mL) it will float in water, and if it is more than 1.0g/mL it will sink in water. So the lower the density, the greater the buoyancy.

The object with the most positive buoyancy. The object with the least density.

Any substance that does not dissolve when placed in water will displace a certain volume. The volume of water that is displaced has a certain weight and the equivalent of that weight of water creates a buoyant force on the object. If the density of the object is less than the density of water then the buoyant force will be enough to make the substance float.

Density of the object and buoyancy of the water/liquid.

"The buoyancy of an object depends on its average density and the density of the fluid in which it floats." "A life jacket provides buoyancy for a person who accidentally falls overboard." "Some floatation materials lose buoyancy after a long time in the water." "The buoyancy of salt water is greater than that of fresh water."

No. Water is incompressible. Buoyancy is determined by density, and being incompressible the density stays the same. Once an object is submerged there's no more buoyancy to be generated.

Buoyancy force is what causes things to float in water. To calculate buoyancy, use Archimedes' Principle: the buoyancy force of a submerged (or partially submerged) object is the weight of the volume of water that the object displaces. In other words, find the volume of the object that is under water, and multiply that by the density of water (1000 kg/cubic meter) and gravity (9.8 meter/sec/sec). It is also density that makes things float in water. If the object has less density than water, it will float.

The more denser an object the less buoyancy.(DrStrong) They are related through Archimedes' principle,FB = ρgVwhere FB is the buoyancy force, ρ is the density of the liquid, g is gravity, V is the volume of water displaced by the object (in other words, the volume of the object that lies underneath the water surface).If FB is greater than the weight of the object, the object will float upwards. If not, the object will sink downwards.So, the denser the liquid, the GREATER the buoyancy. However, the greater the object weight, the less the buoyancy. Another way to look at it is that the object itself has a volume and density, the product of which is the weight. So if a totally submerged object has less density than the liquid, it will be buoyant. If it has greater density than the liquid, it will sink.

Neither, it has neutral buoyancy so will remain where placed.

Buoyancy is the rising of an object through a liquid such as water due to the object being less dense than the liquid. Density is the the mass of an object divided by its volume. Density is often expressed in grams/cm³. For a full explanation of how the buoyancy principle works go to the related question "What is the buoyancy principle?" in the Related Questions section below.

Salinity increase the water density. Therefore the more salt you add to water, the greater its density becomes.The higher the density of the fluid, the greater the mass of the object that can float in it.Hence rise in salinity of a liquid will increase the buoyancy.

It is the ability for an object to float. Buoyancy determines if the object is able to float in the water or not.Buoyancy can not only happen in water, other fluids are not prohibited. Buoyancy can depend on the fluid's density.If something is not or barely able to float, it is less buoyant.If something can float with little or no effort, it is more buoyant.

Density and buoyancy both can hold up water. Buoyancy is how well something will float. Density is the amount of stuff in a certain space.

Is is related through Archimedes principle, which states that the buoyancy force on an object is equal to the weight of liquid displaced by the submerged object. The weight of a volume of water is equal to the volume x density of water x the gravitational constant.FB = V ρ g

buoyancy has to deal with density, gravity, air, and water

its use formula : Fa = density . gravitation . high because water can lift up an object so if an object dipped in water', mass of an object will decrease

Buoyancy is the net upward force experienced by an object in a fluid. Pascal's principle dictates that fluid pressure on an object increases with depth, so there is greater pressure on the bottom of the object than the top, resulting in a net upward force. When an object's buoyancy is greater than its weight, the object will float. An object with neutral buoyancy has a density such that when it is fully submerged the upward force due to buoyancy is exactly equal to the downward force due to the weight of the object. In pure water this is a density of 1000 kg/m3 (1kg/litre) In sea water this is a density of about 1025 kg/m3 (1.025kg/litre) Consider a submarine. A sub with negative buoyancy would tend to sink . Positive buoyancy would cause it to sink. A sub with neutral buoyancy would remain at a steady depth.

From Wikipedia: "If the object has exactly the same density as the liquid, then its buoyancy equals its weight. It will tend neither to sink nor float. An object with a higher average density than the fluid has less buoyancy than weight and it will sink. A ship floats because although it is made of steel which is more dense than water, it encloses a volume of air and the resulting shape has an average density less than that of the water."

Yes, this is the principle of buoyancy. This is what makes balloons float in the air and boats float on water.

Basically, when sugar (or any other substance) dissolves in water, it increases the density of the water. Because the density is greater, the force of buoyancy is greater as well. This occurs because when an object is put in water, the force of buoyancy is equal to the weight of the water that is displaced (Archimedes' Principle). More density means more weight, so even though the same amount of water is displaced, when there is a dissolved substance in the water, the weight of that displaced water is greater. This creates a stronger force of buoyancy.

When there is an object in water, it experiences buoyancy because the water also has weight. The weight of the water pushes the object upwards to make it float.

The buoyant force on an object is equal to the weight of the water displaced by the object. In essence, this equals the product of the water's density, volume of the object, and gravitational acceleration.
