changing mass and volume
Density says how heavy something is, in relation to its volume. If something is dense, it is heavy while being small; something less dense might be bigger but yet weigh less. Density is mass divided by volume.
I would say wish.
When you say one thing is another, it is called a metaphor.
Another way to say 'getting to know', is to say 'getting acquainted with'. You could also say becoming familiar with.
Well The real question is, What is another way to say "came in"
Changing the shape of an object does not affect its density because density is determined by the mass and volume of an object, not its shape. As long as the mass and volume of an object remain the same, its density will remain constant regardless of its shape.
Density is defined as a substance's mass per unit of volume (d=m/v). Another way to say this is how much mass is contained in a set quantity of three dimensional space.
Density = (mass) divided by (volume). You must have known that at some level; otherwise, how did you decide that mass and volume were the things to measure, instead of, say, weight and temperature ?
The amount of substance per unit volume or the number of moles of a substance per unit volume is called its MolarityI think you meant to say "What is the MASS of substance in a given volume called?", meaning what name is given to the mass-per-unit-volume of a substance, i.e. the mass of a chunk of it divided by its volume. The is density.
Mass relates linearly to volume and density. That is to say if you have twice as much volume of the same material (say water) it has twice the mass. If you have something twice as dense at the same volume, it has twice the mass. Note: this applies specifically to mass-density, the most common use of the word. Things like energy-density or population density have a more complicated and often less meaningful relation to mass.
The quotient of mass divided by volume is known as density. Density provides a measure of how much mass is present in a given volume of a substance. It is an important property in determining the physical characteristics and behavior of a material.

Amount of mass per unit of volume
"Practically not at all" is essentially the best answer. High mass/relatively low volume objects (like, say, planets) tend to be approximately spherical.
You have to say what of? Pounds is (sort of) mass and liters is volume.
Temperature will have no effect on mass, however it generally causes the volume to expand (I say generally, because there is a small range in where an increase in temperature cause contraction). Since volume grows and mass stays the same, then density will decrease.
A practical use for density is finding the mass or volume of an object. To find out that mass, say you already have the volume and the density, you would do M = DxV. To find out volume, say you already have mass and the density, you would do V = M/D (/ means divide by the way)
