It means:
* Calculate the density of an object
* Calculate the density of its pieces
* Compare
I am assuming that you mean mass of an object. The answer is no, it does not change. Mass (Density) stays the same wherever the object is, only its weight will change if the force of gravity is different.
The ratio mass/volume is called density.
mass is the density of any given object. what i mean by this is that it is how closely together the molecules are placed, aka the density.
Density is kinda like how much pressure an object takes up. You need to do mass divided by volume to get the density.
Not necessarily. Density is a measure of how much mass is packed into a given volume. An object can have a high density but still be light if it is made of materials that are not very dense. Weight, on the other hand, is influenced by both density and volume.
it means the liquid is heavier. It floats in the liquid.
Perhaps you mean "specific gravity". That refers to an object's density, compared to the density of a reference subtance (usually water). For example, if iron has 8 times the density of water, then its specific gravity is said to be 8.
Density is the ratio of an object's mass divided by its volume. The standard international unit to measure density is kilograms per cubic meter (kg/m3).
The word mass in science means the density of an object.

I am assuming that you mean float (or sink) rather than "slow". Knowledge of density will not help - unless the object is compact. The density of iron is greater than that of water but ships made of iron will float.
Density is simply mass divided by volume, so that would mean either that the object has zero mass, or that it has a huge extension.Density is simply mass divided by volume, so that would mean either that the object has zero mass, or that it has a huge extension.Density is simply mass divided by volume, so that would mean either that the object has zero mass, or that it has a huge extension.Density is simply mass divided by volume, so that would mean either that the object has zero mass, or that it has a huge extension.
