That Depends upon a principle Buoyancy.That means that the object placed in water should have density (particles per unit volume) less than that of water to float or else it will sink. Like when we will put a plastic block in water it will sink but when a bottle made of same plastic block is put in water it floats because it have comparatively lower density to the block due to air.

The general rule is that an object will sink if it has a density greater than that of water.

Why do some objects float when placed in a container filled with a liquid while other sink?

It all depends on the density of the object. If an object was less dense than water, then it will float. If an object is more dense than water, then it will sink.


Why do some objects float and others sink?

Whether an object floats or sinks is a function of its relative density, to the medium in which it is placed. If the object is less dense, it floats, If it is more dense, it sinks. Density = Mass per unit Volume


Why do some object sink in water?

If one cubic centimeter of the object is denser than one cubic centimeter of water, it will sink unless it displaces enough water.

Why does some things float on water while others dont?

Some objects will float on water as the density of the object is less than that of water. Conversely, if an object is more dense than the density of water, then it will sink.


Why do some things float and some dont?

A floating object has a density less than what it is floating in. If an object has more density than the medium it is placed in, the medium will be unable to hold the object. The object will, therefore, sink.


Will cremated ashes dissolve in water?

Some of the ash will, but there will be bone fragments that will sink to the bottom of the water. You can purchase water soluble urns that can be placed in the water. They float for a few minutes and then sink.


Why does some wood sink and some wood float?

There are many different types of wood. Some woods are denser than water and will therefore sink. Some woods aren't as dense as water so will float. Also if the wood becomes saturated when placed in water it will most likely sink.

Why some objects float and some sink?

Those object which have low density then water like wood, ice etc. can flow and those with high density get sink..
