Objects float because of density. All objects are made up of atoms, and atoms have mass. In order to find the density of an object, divide the mass by volume. If the object is less dense the fluid it is in, then it will float.
Because they are less dense than the water.
We call the amount of mass in a given volume of space the density. For instance, we could measure the mass of some fresh water in a container. We would then divide the mass of the water by the volume of the container to find the density. However, if we filled the same container with salt water, it would have more mass because the ocean water has the mass of pure water plus the mass of the salt. Since there is more mass in the same volume, ocean water has a greater density then fresh water.
For something to float, it must have a density that is less than in what it is floating in.
It may seem odd that an enormous ship can float when steel is denser than water. However, if you look at the entire ship you see that there are many places filled with things less dense than water, like air. This means that the density of the entire ship is less dense than that of the water it floats in.
To understand why things less dense then water float in water, go to the question "What is the buoyancy principle?" in the Related Questions section below.

What is the reason why some things float or sink because water is what?
Some things float or sink in water due to their density. Objects that are less dense than water will float, while objects that are more dense will sink. This is because the buoyant force acting on an object in water is equal to the weight of the water displaced by the object.
What are the reason why some things float in the water?
Certain things float in water because their density is less than the density of water. If something experiences more upthrust in water than its weight(upthrust>weight) or upthrust=weight, then it floats in water.
What makes some things float?
Density of the object and buoyancy of the water/liquid.
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.
Why would some things float in lemonade but not pure water?
Some things float in lemonade but not in pure water because lemonade is denser than water due to the added sugar content. The increased density of lemonade provides more buoyant force, allowing certain objects to float that would sink in pure water.
What are some things that can float in water?
Objects that are less dense than water can float in it. Some examples include wood, plastic, cork, and certain types of metals like aluminum. Additionally, objects that are hollow or have air pockets can also float in water.

What are bobwhites?

Why does some things float on water while others dont?
Some things float on water because they are less dense than water, creating buoyancy that allows them to stay afloat. Other things sink in water because they are denser than water, causing them to displace water and sink. Factors like shape, size, and weight can also affect whether something will float or sink in water.
Why does salt water make things float?
salt makes the water denser, so things that are now less dense than the salt water will float
How do things float?
things float because they are less denser then the water. second things do not float, the molecules from the water support the molecules from the thing on the water. that is how something heavy can float. it just has to be boyent meaning it is spread out enough so there is more water molecules to hold it up. if you mean in the air it is the same concept.
What are some things that are buoyant?
Some things that are buoyant include wood, plastic, cork, and foam. These materials are less dense than water, causing them to float when placed in a body of water.
