it can be more or less buoyant be having more or less mass.
i.e. lead will sink in water because the mass is higher and wood will float because it is lighter. the more mass the less buoyant, less mass means more buoyant.

How does salt in water affect the boiancy of an egg?
as the salt dissolves in the water the water becomes more dense, so the egg will be more buoyant. (at least you tried to spell it correctly)
Is an object neutrally buoyant when it displaces an amount of water less than its own weight?
No, it sinks
How does buoyancy affect whether an object will sink or float?
If you just set the object in the water, the buoyant force never becomes greater than the object's weight. It sinks and sinks, displacing more and more water, building up more and more buoyant force, until the buoyant force is equal to its weight. At that point, the net force on it is zero, it stops sinking, and it stays right there (floating). The only way you can produce a buoyant force greater than its weight is to force it further down and hold it there. Since the buoyant force is greater than its weight, as soon as you let go, the net force on it is up, and it'll rise, partly out of the water until the buoyant force drops to equal its weight, and again ... it'll stay right there. So the answer to the question is: An object can't stay indefinitely in a position where the buoyant force is greater than its weight. If that happens, then it lifts some of itself out of the water, reducing the buoyant force, until the buoyant force is again just equal to its weight.
Why does a lemon seed rise and fall in a glass of sparkling water and not in still water?
In sparkling (carbonated) water, tiny bubbles of carbon dioxide can cling to a lemon seed (or anything else in the water) and when they do so, they make the seed more buoyant. The bubbles can also float away from the seed, leaving it in a less buoyant state. As a result, the seed can rise and fall.
Why would a raft float higher in the ocean than in a river?
Salt water contains solutes, and is heavier than pure water. This means that the raft, which will displace its own weight in water, will displace less water (and therefore not sink as far). The effect is that saltier water is more buoyant than less salty water.
Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
By expanding and contracting their swim bladders fish can change their level in water How does this enable fish to become more or less buoyant?
(a) This helps them become more or less buoyant, because if they release the gas then they will sink making it more buoyant by getting air from the surface or from other bubbles it makes them less buoyant, making them float.
What is the the force with which a more dense fluid pushes a less dense substance upward?
the buoyant force
The buoyant force on an object is least when the object is?
The buoyant force is zero when the object is just touching the liquid. As the object displaces more volume, the buoyant force increases until the object is completely submerged. Once the object is submerged, it doesn't matter how deep it is, the buoyant force remains constant.
Are oceanic or continental crusts more buoyant?
continental is more buoyant
Does less ballast makes an object less buoyant?
No, the opposite.
Is a hot-air balloon buoyant?
Yes, hot air balloons are less dense and therefore buoyant ============================================ Hot air balloons are buoyant to the extent that the weight of the hot air in the balloon is lighter than the free air. When the difference is more than the weight of the balloon and its contents it will be buoyant and will ascend.
What makes some matter buoyant?
If the object or matter has a density lower than water does.
What makes objects more or less buoyant than other objects?
Their mass (and the density of the fluid they're floating in).
Are black people less buoyant?
Black children are 2.6 times more likely to drown than whites.
Is there buoyant force on an object at the bottom of an object?
As long as any part of the object ... doesn't matter how much ... is below the surface of the water ... doesn't matter how far ... there is buoyant force on it.
Is there buoyant force on an object at the bottom of the ocean?
As long as any part of the object ... doesn't matter how much ... is below the surface of the water ... doesn't matter how far ... there is buoyant force on it.
