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.

∙ 14y agoWhen a body is completely or partially immersed in a liquid at rest, the liquid exerts thrust at every point on the body in contact with the liquid. The pressure varies with the depth of the point below the free surface of the liquid.That is the upward thrust on the lower part of the body is greater than the downward thrust on the upper part.Hence the body experiences a resultant upward thrust. This upthrust is called buoyancy. Due to this upthrust it experiences a loss of weight

How are buoyancy and density related?
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.
How does an objects volume affect buoyancy?
If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy
The upward force of a liquid or air on an object that helps it float?
The force that makes things float is called buoyancy.
Does the height give any difference in mass?
"Does The Height of an Object Affect its mass?"*short answer - no. longer answer - mass is constant for a given object... WEIGHT is what changes at different heights above earth.*learn to spell, noob!
How negative buoyancy affect a blimp?
Negative buoyancy is when the gravitational pull on a diver is greater than the buoyant force. This means that the diver is being pulled downward, and that the buoyant force is doing negative work (work that is in the opposite direction of the displacement). Positive buoyancy is the opposite situation in which the buoyant force of the diver is greater than the gravitational pull, which makes the diver move upwards. Usually, a person's weight is slightly more than the weight of the displaced amount of water. For example, a person who weighs 80kg displaces 79dm2 of water, which weighs 79kg, that is, he has about 1kg of negative buoyancy. As for your question whether this negative buoancy is a unique feature for black people, the answer is no. it is related to the person's density.
How does object volume affect buoyancy?
If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy
What is the buoyancy of object if it has an area of 31.5 centimeters and a mass of 0.7 kilograms?
The force of buoyancy can only be determined knowing the volume (not area) of an object and the density of the fluid it is placed in. It's value is equal to the weight of the displaced fluid and is independent of the mass of the object.
How is buoyancy related to mass?
Not at all. Buoyancy depends only on the volume of an object in fluid. If buoyancy depended on mass, we would expect that every 1-lb stone should float, whereas every 10,000-ton ship should sink.
How do you measure buoyancy?
place an object in a container with a fluid and find the amount of water it displaced. then find the mass of the object. then multiply the mass by the amount of displaced water♪
In terms of buoyancy how does a life jacket save your life?
A life jacket is also known as a floatation or buoyancy aid - it acts to increase your buoyancy. So what do we mean by this? Well, buoyancy can be described simply as how easily an object will float in a fluid (or gas), where the more buoyant the object the better it will float. Buoyancy is related to the density of an object which is in turn related to the amount of mass a given object has relative to it's volume. As the density of an object gets larger compared to the density of the fluid it is floating in, its buoyancy will decrease and it will become less able to float. As the density of the object becomes larger than the density of the fluid it is floating in, it will sink. Now that we understand buoyancy, we can explain how a life jacket works. A life jacket is mainly filled with gas which has a very low mass. As such when worn by a person, it acts to significantly increase their volume for only a very small increase in their mass. This means that they have a lower density than normal which increases their buoyancy and helps them to float.
Does the mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
How does mass affect the speed of an object?
It has no direct affect on the speed of an object. It does affect the energy content of the speeding object.
How does weight of an object immersed in a liquid affect the buoyant force on the object?
Not at all. (The buoyancy force equals the weight if the displaced water,)
How do you find buoyancy?
Define buoyant mass Mb that represents the effective mass of the object with respect to gravity. Mb=M object (1- Pfluids/Pobject) (/ means divided by)
What makes an object seem to weight less when you hold it in a pool of water?
This phenomenon is called buoyancy and is caused by the object displacing water equal to its volume. If the weight of the object is less than the weight of this displaced water, then the object has positive buoyancy and will float. If the weight of the object is exactly equal to the weight of this displaced water, then the object has neutral buoyancy and thus be weightless. If the weight of the object is greater than the weight of this displaced water, then the object has negative buoyancy and will sink but it still weighs less than it did out of the water.Just remember buoyancy only affects the weight of the object, it has no effect on the mass of the object which remains constant in or out of water.
Increasing the speed of an object does not affect that object's what?
mass
What is buoyancy and how does it affect a blimp?
buoyancy is a measure of how well an object will float in a given medium, eg: a boat in water. similarly for a blimp, the blimp is the object, the air is the medium. if it is not buoyant enough, it will not 'float' in the air, aka fly
