Air has a lower density then water If an object is buoyant in air is it buoyant in water?

yes, because water allows light objects like air to float on it

When the buoyant force on a submerged object is equal to the weight of the object how do the densities of the object and water compare?
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
How does buoyancy and density relate to the world?
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.
What property of an object determines the strength of buoyant force that will be exerted on it when submerged in water?
Density - esp relative to water.
Will an object with higher density displace more water than an object with lower density?
no
What can be assumed about the buoyant force on an object floating in water?
The buoyant force on a floating object is equal to the object's weight out of water.
What makes some matter buoyant?
If the object or matter has a density lower than water does.
If an object is buoyant in air is it buoyant in water?
Yes, since the density of air is less than the density of water, a buoyant object in air is buoyant in water. In any body of water that is exposed to the air, in fact, said object would escape the body of water entirely.

Do boats float higher or lower in tropical waters?
higher as when the temprature rises the density of the water/liquid decreases, so does the buoyant force that the water/liquid exerts on an object such as a boat or vessel

An object with a mass of 4.6 kilograms and a volume of 0.0025 cubic meters is submerged in water. What is the buoyant force on the object?
The buoyant force is equal to the amount of water displaced. Multiply the volume of the object by the density of water - then convert that to a force (at about 9.8 newton/kilogram).
Why does a rock has to sink?
A rock sinks because it is not buoyant. Buoyancy is whether or not something floats in water. There are three levels of buoyancy; buoyant, neutrally buoyant, and not buoyant. When something is buoyant, that means it has a lower density than water, causing it to float. When something is neutrally buoyant, that means it has roughly the same density as water, causing it to float half way between the bottom and the surface. Finally, when something is not buoyant (like a rock), that means that it has a higher density than water, causing it to sink to the bottom.
How is buoyancy figuired?
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.
How does density affect buoyancy?
Ignoring shapes (using cubes), density (mass/volume) greater than "water" means it sinks. The floating object displaces its weight of the buoyant "object" (water, etc.)when it floats, but displaces its volume when it sinks.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
