What causes the buoyancy to increase or decrease?
Buoyancy force come from difference in density of the object and the surrounding. Buoyancy of the ship can change from the pay load inside its' space. More load per space reduce the buoyancy. For Balloon, buoyancy is change by increase temperature of gas inside to balloon since increase in temperature would cause gas to expand and had lesser density in its' cavity. In general, buoyancy increase or decrease by changing of density of the object or the surrounding medium.
What are facts about buoyancy?
buoyancy has to deal with density, gravity, air, and water
How do you use buoyancy?
Buoyancy is what keeps a boat floating on the top of the water. Buoyancy is what makes a helium balloon float in the air.
Does buoyancy help people stay on the ground?
No, it does not. Buoyancy keeps things afloat in water.
How does buoyancy occur?
Buoyancy occurs in fluids, which are gases and liquids. Hot air balloons are buoyant in air and ships are buoyant in water for examples. When the buoyancy of objects exceeds the weight of those objects, the objects rise. When the weight exceeds the buoyancy they sink. And when the buoyancy equals the weight of the objects they float.
Why does a submarines density decrease when it pumps air out?
It doesn't pump air out; it forces water out of its ballast tanks to increase its buoyancy.
Does buoyancy increase or decrease when heat is added?
it decreases
What affect provided by water aerobics helps make the exercise beneficial?
Buoyancy
How buoyancy force works?
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
How does buoyancy affects a boat?
Buoyancy affects a boat by keeping it "on" the water, not "under" the water.

How does salt reduce buoyancy in water?
Salt actually increases buoyancy.

What happens to water if the salinity increases?
The heat capacity and freezing point decrease, evaporation slows, and osmotic pressure increases.
Does buoyancy have anything to do with your human body being able to absorb water?
no, buoyancy is when something floats on water
Do airplanes fly because of buoyancy?
No. Buoyancy refers to the ability to float in water.
How can buoyancy be demonstrated?
buoyancy can be demonstrated if you float something because buoyancy is when something floats for example a boat floating in water
