Two bubbles less than a millimeter apart might have radically different temperature, density, and other important properties.
This is the downside of density: when something goes wrong, it happens to a lot more people.
It took us about 15 minutes to come out of the subway because of the density of crowd.
A new urban revolution is upon us, driven in large part by the returns to density, skills, and creativity.
Second, everyone who actually studies the subject—save Kotkin—agrees that cities and density spur economic growth.
If the density be inversely as the distances, the periodic times will be equal.
So if rate of speed and elasticity be known, the density may be computed.
This supposes that the density of the stars in each part of the Galaxy is the same.
In this way the density of the ether has been deduced by noting the velocity of light.
Beyond this the density sinks to less than 200 per hectare and less than fifty on the outskirts.
density den·si·ty (děn'sĭ-tē)
The mass per unit volume of a substance at a specified pressure and temperature.
The quantity of something per unit measure, especially per unit length, area, or volume.
A measure of the quantity of some physical property (usually mass) per unit length, area, or volume (usually volume). ◇ Mass density is a measure of the mass of a substance per unit volume. Most substances (especially gases such as air) increase in density as their pressure is increases or as their temperature decreases. ◇ Energy density is a measure of the amount of energy (often in the form of electromagnetic radiation) per unit volume in a region of space or some material. See also Boyle's law.
