There may be a quiz de la pop tomorrow on the stuff we talked about in class (the types of matter, the kinetic theory of matter, etc)…

Here are the notes from today…

I.  Describe the four states of matter.

Tiny particles in constant (1) __________________ make up all matter.

All
matter takes up (2) _____________ and has (3)__________________.
However, matter can exist in different states.  The state of matter
that something has depends on one thing - (4) __________________. 

For example, water exists as (5) __________________ at low temps,

(6)__________________ At moderate temps and (7) __________________
          at high temps.  At even higher temps, the matter in water becomes   

(8)__________________.

          So, the four states of matter are (9) __________________, (10)

__________________, (11) __________________ and (12)

__________________.

                Each of these state has (13) __________________ that are used to   

      identify it.

II. Use the kinetic theory of matter to explain the characteristics of solids, liquids and gases.

Solids

Every solid has a definite (14) __________________ and a definite (15) __________________.

Why
do solids have these characteristics?  Tiny particles in constant
motion make up all matter.  This is called the (16)
____________________________________. 

          The particles in solid matter are held close together by

(17) __________________ between them.

          The particles in a solid can vibrate close to their neighbors, but they lack

enough (18) __________________           to move out of position.  This is

why you can’t squeeze a solid into a smaller space.  So, a solid always has               the same shape.

                 In most solids, the particles are arranged in repeating geometric patterns

      called (19) __________________ .  Different solids have crystals of

      different (20) __________________.

                            Some materials that we think of as solids are not made of

                  crystals.  For example glass, plastic, some kinds of wax, etc 

                  appear to be solids but are not made of (21) ______________.

                                       They are often called (22) __________________ solids. 

                             In many ways, these types of solids have properties
                                       closer to thicker liquids than normal crystal solids.

Liquids

A
liquid has a definite (23) __________________.  However, unlike a solid
a liquid will tkae the same shape as its container.  So, a liquid can
change (24) __________________. 

Just
as the kinetic theory (motion of tiny particles) expalins the
properties of solids, it also explains the properties of liquids.  The
particles in a liquid have enough (25) __________________ to move over
and around each other.  This allows a liquid to (26) __________________.

          However, since the particles in a liquid are held very close to one another,

liquid does have definite (27) __________________.

Gases

Gases have neither a definite (28) __________________ nor a definite (29) __________________.

According
to the (30) __________________, the particles of a gas have enough (31)
__________________ to separate completely from one another.  So, those
particles spread evenly throughout their container.   

Plasma

Even
though we are most familiar with solids, liquids and gases…. none of
those is the most common state of matter in the universe.  The most
common state of matter in the universe is actually (32)
__________________.

Plasma is a gaslike mixture of (33) __________________ and (34) __________________ charged particles. 

An example of plasma that you can observe is found when a (35) __________________ is switched on.
