If mass is constant, density goes down as volume, or quantity, goes up.
In other words, if there is more of something (or it is bigger in size), and it has the same amount of matter, then it is less dense. This is because the atoms/molecules are spread out more.

The fundamental density is the ratio of the mass of a substance to its volume this is known as what?
its density. note. density is often expressed as the ratio of the density of the substance to the density of water at standard temperature and pressure. This is known as the specific gravity of the substance. It is a dimensionless number so it has no units.
What are two reasons why density is a useful property for identifying substances?
Density is specific for each substance. Also the measurement is generally simple.
Is 'small' a qualitative or a quantitative property?
A qualitative property is one that defines something based on characteristics such as color or density. It refers to the description of a substance rather than a measurement of that substance. A quantitative property deals measurements of a given substance and can be expressed as a number or quantity.
Determines if an object will float or sink in a fluid?
Density. An object will float in a substance if its density is less than the density of the substance. The density of water is 1 kg /L or 1 g/ cm3. Anything with a density less than this will float.
A solid has a volume of 24cm3 and a mass of 60g. What is the density?
The density of a substance is often expressed in units of grams per milliliter. If a substance with a volume of 60 ml weighs 85 grams the density is found by dividing the weight (85g) by the volume (60ml). This substance has a density of 1.42g/ml
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
What is the effect of shape on the density of samples of the same material?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
How do you calculate two densities in order to find the density of the combined substances or objects?
To get the average density of the combination, you need to divide the total mass by the total volume. Just knowing the density of each substance you combine is thus not enough; you also need to know how much quantity of each substance is involved.To get the average density of the combination, you need to divide the total mass by the total volume.

How does volume affect specific gravity?
Specific gravity is otherwise known to be "Relative Density". It is the ratio of the density of a substance to that of water as water has been taken as standard. So though volume gets changed there is no chance to get change in the relative density as it is the characteristic property of the substance.
Is the density of a kilogram of iron less than th density of one gram of iron?
The density should be identical regardless of the quantity, because "density" is what's called an intrinsic property; it doesn't matter how much of the substance there is.
Why is the density of a substance independent of sample size?
Density is an intensive quantity which means it is independent of size. This can be seen from the definition of density. Density = mass/volume So if the sample size increases than so does the mass, but the density remains unchanged.
Does shape affect density?
The shape of a substance does not affect density of a substance. The density is a physical Quantity which is predefined and constant for each substance. By the equation Density=mass/volume It is clear that the density is affected by mass & volume of the substance and not the shape. However the shape of a substance affects the area acquired by the substance. Like every natural body is spherical in shape like river stones,asteroids,planets,raindrops,dewdrops because they try to acquire the minimum possible area and sphere is the only geometrical figure occupying minimal area.
Does the solutes density effect rate of solubility?
no.Concentration is the amount of substance present in a given quantity of another substance. It is thus a quantity or number of atoms present in a unit volume of another substance. The first substance could be solid, liquid or gas. This is called a solute and the substance in which it is added is called solvent. This solvent is generally liquid.Density is defined as mass per unit volume of a substance. Generally, the density of an object is the total mass of the object divided by the total volume of the object. This object is generally a solid or liquid. Thus, density and concentration are related terms dealing with concentration in general. Concentration deals with small particle while density is concerned with the mass. Thus, concentration is directly proportional to density for elemental substances but not in general.source: http://www.blurtit.com/q633112.html
How does phase change effect the mass of a substance?
Phase change doesn't effect the mass of substance. However, it cause drastic change of density and the weight of substance may change due to buoyancy force.
Describe the effect of temperature on density currents?
when a substance is cooler at the surface, the density increases in the substance.
Which classification of property does not effect density?
Intensive property is the classification of property that does not affect density. In science, there are ten intensive properties of a substance.
How do you determine the density of a granular substance which is insoluble in water?
Using Archimedes principle we can find the density of such object. First let's weigh the body hanging in air using a physical balance. Let it be w1 Now immerse it in water kept in a beaker and weigh once again. Let it be w2. Now using the expression density can be found. Density = w1/ (w1 - w2)
