@it's called buoyancy because some things are heavier than others .......................... that is a good theory but no, buoyancy does cause it but buoyancy also needs air pressure took keep afloat .

What causes certain liquids to float above others?

the density of each of the fats. the higher density, the lower it will be in a mixture


Why do things float but not others?

because of buoyancy!


What force causes things to rise or float?

Buoyancy is the force that causes things to rise or float in a fluid, such as water or air. This force is exerted in the opposite direction to the force of gravity, making objects appear to be lighter when submerged in a fluid.


What makes certain substances float and others sink?

Substances with a density (mass per unit volume) greaterthan a liquid will sink in the liquid; if the object has a lower density it will float.


Would the force that causes a helium balloon to rise be called anti-gravity?

No, it rises because of buoyancy. For a really good non-mathematical explanation go to the answer in the Related Answers section below called Why do some things float but not others.


What is a liquid that makes things float?

It is quite common for various things to float in water. But any liquid can cause things to float.


How do you make things float?

You can't make things float, things float by it's self's it's density is lower than 1 it can float, if it's density is greater than 1 it can't float.


Why do some things flaot while others sink?

Some things float or sink based on their density. Objects that are less dense than the liquid they are placed in will float, while those that are more dense will sink. Additionally, the shape and size of an object can also affect whether it floats or sinks.


Does salt water float?

On some liquids it will float, on others it will not.


What are the reason why some things float in the water?

Things float in water because of buoyancy, which is the upward force exerted by a fluid that helps objects float. Objects will float if they are less dense than the water they displace. This is why materials like wood and plastic, which are less dense than water, float.


What causes thing to float in the ocean water?

Atoms like oxygen and hileum like a water bottle floating but only when it has oxygen in it. If you crushed the bottle it will have less oxygen making it not float but not all atoms make things float. Also your welcome if it helped.


Why a cork float in a salt water?

The salt in the water causes everything to have more buoyancy (Meaning it makes things more likely to float.) If you die in the ocean your body is more than likely going to float unless it is attached to something heavier is attached.
