Objects float because their density is less than the density of the liquid on which they are resting. In other words if you made a mold of an object and an object weighs less than the water that would fill the mold, the object will float.

∙ 14y agoBecause they have gasses inside like oxygen hydrogen etc. It has to do with water displacement. An object floats because it displaces the water that it sits upon. If it cannot displace this area, it will sink. Displacement means that the weight or volume of a fluid displaced by a floating body, used especially as a measurement of the weight or bulk of boats or ships.

∙ 13y agoBecause the floating object weighs less than the water (or liquid) it displaces. I think this has to do with density. At room temperature water has a density of a little less than 1000 kg/m3. In other words, water weighs 1000 kg for every cubic meter. If an object weighs less for every cubic meter it will float. If it weighs more for every cubic meter it will sink. The same happens with liquids and liquids, solids and solids, gases and gases, gases and liquids, liquids and solids. Steam will rise above the cooler air. Bubbles will rise up through water. Boats sink into the ocean. I'm not sure how this works at a molecular level.

Why do some objects float and others dont?
Because some objects are a lot denser than water so the sink and others are less denser so they float
Objects float in water because water has an?
Objects that float in water have a lower density than water. -anonymous18_K
Do peanuts float in fresh water?
Yes. The salt stabalizes them in the water. If you have ever heard of the dead sea, anything really can float in there. If there is salt in water a peanut can float.
Why do some objects float or sink in water?
It depends on the density of an object. If the density is higher than the density of the liquid, the it sink. If it's less, it floats.
Do ginger people float or sink in water?
no they dont float like normal people
Why do some objects float and others dont?
Because some objects are a lot denser than water so the sink and others are less denser so they float
Do all objects float?

What is the answer to the question does an object float in saltwater freshwateror neither?
It's far from clear what the actual question is. Some objects float in both salt and fresh water, some objects float in neither, and some objects float in one but not the other. Any object that floats in fresh water will float in salt water, but the reverse is not true.
What type of objects will float on top of water?
The types of objects that will float on water are foil, most rubber, and some plastic.
What are objects will sink and what objects float?
it will float
Why does some objects sink and some float?
It is to do with to volume and mass.
What are some objects that float and breaks easily?
Styrofoam
Why do some objects float and others do not?
because some objects are much denser(heavier) than water so they sink
What objects float in water?
objects that are less dense float to the top.
Why do some object float on others?
Because some objects are heaver than others.
What objects will float sink then float?
A submarine
Why some things float and other things sink?
Because of the objects density.
