Objects sink or float depending upon their densities. For example wood floats on water because the density of wood is less than that of water, while a piece of iron would sink in water as its density is more than water.

Why do things sink or float in oil?

Things sink or float in oil based on their density. Objects that are less dense than the oil will float, while objects that are denser will sink. This is due to Archimedes' principle - an object will float if the weight of the fluid it displaces is equal to or greater than its own weight.


Why do things float and some things sink?

Objects float or sink based on their density relative to the fluid they are in. If an object is less dense than the fluid, it will float; if it is more dense, it will sink. This is due to the buoyant force acting on the object, which is the result of the pressure difference between the top and bottom of the object.


Why some things float and other things sink?

Because of the objects density.


Do the most dense things float or sink?

The density of an object determines if it sinks or floats. If an object is more dense than the medium it is in, it will sink. If it is less dense, it will float. Therefore, the most dense things typically sink.


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.

Why does only light things float in salt water?

Whether things float or sink this depend only on the density , the density of the salt water is aprox. 1030 kilogram per meter cube so if you but things have density less than that they will float , things with higher density sink.
