# Density Essay

how could I write an essay on density?

First you write down all the main points about density, then you arrange them into an essay. Heres where you can read about density (http://en.wikipedia.org/wiki/Density)

Paragraph one:

• give some brief information about density
• mention the 3 different subjects your going to talk about (For example: the history, the measurement, common units)

Paragraph two: Talk about the first point (in my example would be ‘the history’

Paragraph three: Talk about the second point (in my example would be ‘the measurement’)

Paragraph four: Talk about the third point (in my example would be ‘common units’)

Paragraph five:

• this is your conclusion paragraph
• gather any loose information you haven’t mentioned

DENSITY is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative “heaviness” of objects with a constant volume. For example: A rock is obviously more dense than a crumpled piece of paper of the same size. A styrofoam cup is less dense than a ceramic cup. Density may also refer to how closely “packed” or “crowded” the material appears to be - again refer to the styrofoam vs. ceramic cup.

he formal definition of density is mass per unit volume. Usually the density is expressed in grams per mL or cc. Mathematically a “per” statement is translated as a division. cc is a cubic centimeter and is equal to a mL Therefore, Density = mass volume = g/mL

Mass vs. Weight: Although the terms mass and weight are used almost interchangeably, there is a difference between them. Mass is a measure of the quantity of matter, which is constant all over the universe. Weight is proportional to mass but depends on location in the universe. Weight is the force exerted on a body by gravitational attraction (usually by the earth).

Example: The mass of a man is constant. However the man may weigh: 150 lbs on earth, 25 lbs on the moon (because the force of gravity on the moon is 1/6 that of the earth), and be “weightless” in space.

If the density of a substance and either mass or volume is known, volume or mass, respectively, can be calculated using either simple algebra or dimensional analysis. The density must be translated as a conversion factor.
