Because density is a "ratio".

Why id density a useful property for identifying substances?
It is useful because no matter how much you have of the same substance, it will always have the same density. The mathematical equation to find the density of matter is to divide the mass by the volume. So you get an average, the density. Water has a density of 1. However, oil has a density of something like .9, so it floats on water. That way, by just looking at the numbers, you can tell what is what.
The density of a quart of water and the density of a teaspoon of water are the?
Yes it would. In fact, it IS.Density is a property of the substance, no matter how much or how little of it you have.Whether a droplet or an olympic swimming-pool full, water is water, and has the density of water.
What is always the same no matter how much of the substance you have?
mass
If 2 pure substances have the same density are they same substance?
No, at a different temperature and pressure the volume of any substance increases or decrease (depending on Temperature and Pressure). Also the severity of the volumetric change depends on the state of the substance. Because density=mass/volume and the volume changes while the mass doesn't the density WILL change slightly in solid phase, noticeably in the liquid phase and significantly in the gas phase regardless of weather or not the substance is pure
What is an example for an intensive property?
Intensive properties are those properties that are independent of mass or size. Examples would be temperature, density, etc. Regardless of how much you have, the density is the same, and the temperature is the same.
Does there density of object change when there is more present?
No. Density is a characteristic property, so there it is always the same no matter how much of the substance is present.
Why density does not change with volume?
Density is how tightly packed the matter in a substance is. Therefore, how much space it takes up (volume) will not affect this.
Will the density of gold ever change?
No density of a object (mostly solids) never change not even when gold is in a ring or a necklace. Because in my science book it states "Density is a physical property of a substance. Density is the same for a substance no matter how much it is measured"
Does density change if the sample of the same matter is larger?
No density if a characteristic of matter. Density can vary with temperature and pressure, but a chunk of something twice the volume of another chunk of the same substance will weigh twice as much because the two chunks have the same density.
Is density a measure of how much light is reflected in a substance?
hell no! density is the ammount of matter per unit of measurement.
Does the density of a substance change depending on how much of it you have?
No. Density is an INTRINSIC property, and as such it does NOT depend on the size of the sample.
Is density of you beam the same with density of steel?
The density of a substance stays the same, no matter how much space it takes up.
How many milliliters in 650 milligrams?
That depends on the density of the substance. The density tells you, precisely, how much mass a substance has per unit of volume.That depends on the density of the substance.

The density tells you, precisely, how much mass a substance has per unit of volume.
By how much does the density of air increase when it is compressed to half its volume?
Density is inversely proportional to volume. If volume changes to half, density doubles. The substance doesn't matter.
What property of matter changes depending on the gravitational pull?
Weight
Does the amount of a particular matter affect its density?
The simple answer to this would be no. Density is the mass per volume of a substance so if you were to add either one of these quantities the other would have to rise by a proportional amount and the density would remain constant. However this become untrue when the amount of matter you are dealing with become on the order of a planetary mass. This much matter will produce a gravitational field which will cause pressures to result that will be enough to invoke a phase change in the portions from the center of the mass on outwards. In this case the density will change with the change in phase.
Does a substance change mass if it changes physically?
No. Mass is a measure of how much matter is in an object, and that does not change when the matter changes states. The matter will either contract or expand, depending on the current state and the state to be reached, but that does not change how much matter is in the object.
