if the density is lower than the liquid it will float, if it is higher it will sink, this doesn't take into account things like ships though since the density of the hull is obviously more than water but the total density including all the free spaces within is less

The density of the mass of the object suspended in the liquid (water, I assume).
If the density is greater that the H20, things sink. If the density is less than H20, things float.

It has to do with something called buoyancy. When you throw something into the water, it pushes away, or displaces, a certain amount of water. For instance, when you dunk a tennis ball into a full bathtub, a tennis ball amount of water spills out the side. If the weight of this displaced water is heavier than the weight of the tennis ball, then the tennis ball will float. If the ball was filled with lead instead of air, it would be heavier than the amount of displaced water and would sink. The man who discovered this was a Greek mathematician called Archimedes, who is known as the father of buoyancy. He figured it out, not surprisingly, in the bathtub!

Densities. If an object is more dense than the water that it lands in, it will sink. If not, it will float.

Densities. If the object is more dense than the fluid it is in, it will sink. Less dense, and it will float.

densites is why things float if you put a sponge in water you can see it float cause of all the holes

submarines deal with this question every day. They've got it all figured out so it make sense to review what they do.

It depends if the object is heavier or lighter than water

If you want a scientific answer, some things are denser than others.

they have different density's it has nothing to do with how big an object is
