Nothing happens to the density. It's a property of the <substance>. The density is the same regardless of how large a piece you have. That's why density is a useful concept. It tells you something that's true of the <substance> regardless of what size sample you're holding.
A large block of ice has the same density as a small ice cube.
The 49¢ sample of Acme soap has the same density as the $1.49 family-size bar of Acme soap.
Density means, how much stuff (mass) divided by volume (the space the stuff occupies). If we make the space occupied smaller the density goes up - we squash the stuff up more, in other words.
Increases.
Well you Find the density by doing Mass/Volume. If The objects density is less than 1 it will float
Density. Mass is the product of volume and density, so therefore density is the ratio of mass to volume.
The objects density has to be less than that of water (which is 1000kg/m3).
An object can float on water only if its density is less than water.(Archimedes principle). So, to make an object float, its density should be low. For this purpose, its mass should be less and volume should be greater(d=m/v), so to make heavy objects to float, their volume should be as less as possible.

There is a general tendency for objects to expand when they get hotter - this includes air, and gases in general. As a result, they have less density (mass per unit volume); and objects with less density tend to float or rise.

It depends on the density of a material. The density can be calculated using: density = mass/volume. This means that a very heavy object like a tanker can float on water because it has a large volume which makes its density less than that of water.
Density. Mass is the product of volume and density, so therefore density is the ratio of mass to volume.
If an objects density is less than the density of what it is put in it will float. If the objects density is greater it will sink.
Density is a characteristic of a given material. Water, for example, has a certain density (which is somewhat dependent upon temperature but let's say that the temperature is constant). It does not matter how much water you have, it will all have the same density. One teaspoon has much less mass, but the same density as an entire ocean.
Greater the mass higher the density and less the mass lower the density as D = M/V For fixed V, density is directly proportional to the mass.
objects that are less dense float to the top.
You seem to be thinking that density is the same as mass, or proportional to mass. That is not the case. Density is mass divided by volume. For example, two objects of the same material have the same density. The larger object will have more mass (in the numerator), but it will also have more volume (in the denominator).
The formula of density is: d = mass/volume.
The objects density has to be less than that of water (which is 1000kg/m3).
