Title: The Basics of Matter
Description: An old essay I wrote back in school, this is a good document for the basics of matter. It includes basic equations, the structure of matter, laws related to matter, and anything else that someone would need to know about matter before going into chemistry or physics.

Matter
Chemistry Essay
A scientist may mix together chemicals and wonder “What is this? What are
these classified as, and why do they change?” To chemistry, the objects are matter, the
building blocks of the universe and the ingredients of existence, structures that
commonly come in the form of solids, liquids, and gasses
...
While it may be eternal, and is anything taking up any
amount of space with a measurement of mass, it doesn’t always remain the same; it
can change
...
Properties of matter aren’t just characteristics; they are parts of matter that can or
cannot change
...
An example of one of those many
properties is color
...
However, the other type
of property, extensive properties, does indeed alter based on the amount of matter
present
...
If the box full of iron was put onto a weighing scale, the
measurement of gravity attracting objects towards Earth (weight) would change if any
said amounts of iron were to be added or subtracted to the box
...
Rust
isn’t just a redcolored material that forms on metal; it is a chemical property commonly
found on iron
...
The properties of matter explain what characteristics it has
...
Reactions are processes chemists study and are significant to chemistry in how
they show particles that interact with change
...
Bending an object is one type of force
...
Differently, chemical changes are an example of substances’ structures
being changed
...
For
example, when 2 atoms of hydrogen are combined with a single atom of oxygen, a
chemical reaction occurs and creates H (water)
...
A
chemist would try and discover new properties about a substance and see what
physical and chemical reactions it has
...
Reactions, physical and chemical, are important attributes of chemistry, but aren’t just
simple changes; reactions tamper with the complex structure of matter
...
The structure of any form
of matter can consist of the following: atoms, elements, compounds, and mixtures
...
Because of these chemical ingredients that make a substance,
there are two types of substances, the first being a heterogeneous substance
...
Oil and water put together in a jar (as shown in
one of our LABS) make a heterogeneous substance, as the oil’s mass is low and can
float on top of H, making the substances visibly different to the naked eye
...
Table salt is a pure homogeneous substance, and is defined as so
because the elements in it (sodium and chloride) are viewed as one compound, NaCl
(sodium chloride) and don’t appear as separate elements
...
The law of Conservation of Mass (discovered by French Chemist Antoine
Lavoisier in the 1700s) is important because it shows how closed and open systems
differ with the fact that matter cannot be created or destroyed, but can be rearranged
due to chemical reactions
...
If
a reaction such as heat being added takes place, matter isn’t created or destroyed, and
the mass of the reactants is the same of the products created from the energy of heat,
like what I did in one of my LABs in which I burned a chemical powder with the light of a
candle, which then turned into a rubberlike substance, but still had the same amount of
mass
...
In a closed system, only energy (such as heat or kinetic
energy) can be exchanged with its surroundings, but matter is not, thus the mass of the
objects in the system cannot increase or decrease
...
However, an open system is much
different
...
A large
example of this is the Earth, as it absorbs both energy from the sun and matter such as
space junk
...
Matter is what the universe is made of, the building blocks that take up space
...
Matter has intensive and
extensive properties, changeable by physical and chemical reactions
...
But
matter isn’t material just lying around; it’s a tool that humans have found ways to use
...
Space engineers have thought of a rocket engine that uses plasma (a form of electrical
matter that contains positive ions and negative ions or electrons) to power it, and could
go up to 123,000 miles per hour to launch astronauts to planets such as Mars and
continue exploration of the cosmos
...
Matter is the soul of chemistry and many
other sciences, the reason people study these subjects in the first place
