It depends on the state of the fluid, liquid or gas. If air is liquefied and water is turned into a gas then water will be more buoyant. At STP air is more buoyant. Water. Air is not a fluid - but it does have some fluid properties.
Between the two air is more buoyant.

Which fluid produces the greater buoyancy force - air or water?
Buoyant force is dependent on the density of the fluid. Since water is denser than air (by a lot), an object immersed in water will experience a much greater buoyant force than one surrounded entirely by air.
How does salinity effect buoyancy?
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.
What law explains the floating of objects on water?
You need to explore the following topics: 1) Pascal's Principle, 2) Buoyancy, and 3) Archimedes' Principle.In a nutshell, objects submerged in a fluid such as water will experience an upward force that is proportional to the size of the object. That upward force is called buoyancy. If an object's buoyancy is greater than its weight (which is a downward force), the object will float. If the buoyancy is not sufficiently large to overcome the weight, the objects sinks.
What do buoyancy and displacement have in common?
well buoyancy is wether somthing floats sinks or stays in the middle of a liquid and displacement is how much liquid is "moved" by an object being put into it ( example: fill a cup full, put ice in it, it overfolws ) so in common they both have to do with liquids and how they react to cirten objects.
Why are forces exerted on a submerged object due to water pressure not balanced?
Forces are exerted on a submerged object due to water pressure not being balanced due to buoyancy. This is when the pressure at the bottom of the submerged object is greater than the fluid on the top of the object, thus projecting the object upward.

Buoyant force is dependent on the density of the fluid. Since water is denser than air (by a lot), an object immersed in water will experience a much greater buoyant force than one surrounded entirely by air.
How is fluid used to lift heavy objects?
Water helps lift an objects via the buoyancy force. The buoyancy force is equal to the weight of water displaced by the volume of the submerged object. If this buoyancy force is equal to the weight of the object, the object will float in that position. If the object is completely submerged and the resulting buoyancy force is less than the weight of the object, it will continue to sink.
How does salinity effect buoyancy?
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.
Why clip can float on water?
Assuming the paper clip to be made of iron or aluminum To understand this you will need to study buoyancy and stuff... let me explain buoyancy in a nutshell, buoyancy is the upward force exerted by a fluid( gas or liquid) on any object partially or fully submerged in it. for example, when you try pushing a plastic beaker in a tumbler of water, you would have definitely felt a push this is buoyant force. buoyant force = volume of object immersed * density of the fluid * g. As a paper clip possesses a greater volume it experiences a greater amount of buoyancy which keeps it afloat. however a nail which has a comparable lesser volume sinks. hope it helps
Do buoyancy work only in water If No then where else can it work?
Buoyancy can work in any liquid provided that the object floating weighs less than the liquid it displaces. This is true regardless of whether it is water or not! Buoyancy works in any fluid. The fluid can be any liquid, or any gas.
Why doesn't a sugar cube float in water?
Sugar dissolves in water.

What floats and sinks in water?
It depends on the buoyancy force if the weight is greater than buoyancy force it will sink other wise it will float.

Why is the buoyancy force of dead sea so large?
The extreme salinity - saltiness - means the water there has a higher density than regular sea water. and the higher the density the greater the buoyancy.
What liquids have a better buoyancy?
Liquids that have a greater density than water, will provide more buoyancy to objects floating in it. Salt water is more dense than fresh water, so objects will float higher in it.
Does buoyancy change with depth?
The buoyancy of an object submerged in water does not normally change substantially with depth, but there are caveats to this answer. The buoyant force is equal to the weight of fluid displaced. In the case of non-compressible liquids the buoyancy force does not change with depth. No material is truly incompressible, so if you go really deep (the bottom of the ocean for example), the fluid is compressed a little bit, and so a given volume of the fluid is heavier (denser) and the buoyancy force is greater. (The difference in the density of sea water between the surface and the greatest depth of the ocean is only a few percent.) Buoyancy forces are also present in compressible gases, for example, a balloon in Earth's atmosphere. In this case, air closer to the Earth's surface is more compressed and thus significantly denser, meaning a fixed volume object will experience a noticeably greater buoyancy force at lower altitudes. Finally, the buoyant force can change with depth because the volume of the object changes with depth. Certainly this is an important factor with balloons in air and if you submerged a balloon in water the effect of pressure on the volume of the balloon would be a dominant factor on buoyancy. This is present, though small, for solid objects as well. One more thing, if you are being really picky, gravity changes with depth as well and so affects buoyancy. Obviously not important on Earth, but dropping a mass into a gas planet does have to incorporate the change of gravity with depth and all the other caveats mentioned above.
