An object will float on water if it has less density than water.
The property of water that allows things to float is buoyancy. Water exerts an upward force on objects placed in it, which counteracts the force of gravity pulling the objects down. This buoyant force is what allows objects to float in water.
Yes, water can float on water. This is because of surface tension, which allows objects with a lower density than water to float on its surface. Items like boats or water bugs can float because of this phenomenon.
They can float without salt - It's the ratio of water displaced by the object in relation to its weight of the object that allows it to float - not the salt content of the water.
Objects that float in water have a lower density than water. -anonymous18_K
Objects that float on water are less dense than water, which allows them to displace enough water to support their weight and remain on the surface. This is due to the principle of buoyancy, where the upward force exerted by the water is greater than the downward force of the object's weight.

The types of objects that will float on water are foil, most rubber, and some plastic.
The density of ocean (sea) water is approximatley 1.025; the density of the human body is approximately 1.00; less dense objects float on top of or near the surface of denser liquids. The saltier the water or the more body fat you have (body mass index), the better you float. Cheers Malcolm
Objects that are denser than water will sink, such as rocks, metal objects, and certain types of wood. Objects that are less dense than water will float, such as plastic bottles, rubber ducks, and foam.
objects float better because chemicals help make the objects float higher. the more salt the higher the things go
an object will float on salt water best
salt water is different from tap water. when salt is added to water it converts the tap water to salt water. This increases the density of the water, and allows more objects to float above it. remember, when objects are mixed like that, the greater the density, the further it is from the surface.
