    Kinetic Theory of Matter

    The kinetic theory of matter states that all matter is composed of tiny particles that are constantly in random motion. The amount of motion and interaction between particles depends on temperature - as temperature increases, particle motion and separation increases. This theory explains the different states of matter as a function of particle energy and interaction: in solids particles are tightly packed and vibrating, in liquids they have more space and can flow past one another, and gases have the most separation and particle independence. Changes between these states, like melting, boiling, and condensation, occur when temperature changes alter particle motion and interaction.

    __Kinetic Theory of

    Matter__

    The Kinetic Theory of Matter is a reasonable


    explanation...

    ...that states that matter is composed of small


    particles in random motion.
    When the temperature of matter increases, its
    movements also increase.
    MATTER
    Firstly, what is matter? Matter is what all physical objects are made of. All matter takes
    up space. There are four states of matter that people are most familiar with: solids,
    liquids, gases, and plasma.

    SOLIDS

    Solids are atoms and molecules (particles) that are so closely


    packed together that they form a specific shape and volume. They
    are so close together and stay together so strongly that they are
    able to maintain their shape. They also move! There are little
    vibrations that we do not realize because they are so compacted
    and small. Examples of solids can be a bar of gold, your pencil,
    your desk, and things of the sort.

    LIQUIDS

    Liquids are particles that are a little less closer than what solids
    are and have enough energy to move around a little. Because they
    are close enough, their forces allow them to form the shape of
    what holds them while they can also move around—or
    specifically, flow about. Just think of a glass of water. Water
    poured into a glass form the shape of that glass. It will flow if you
    give energy to it. That energy can be your shaking of the glass.
    Examples of liquids can be the ocean, juice, blood, and things of
    the sort.
    GASES

    Gases have no definite volume or shape and are particles with a


    larger separation between each other. They do not have any
    forces. The average distance between these particles are usually
    10 times greater than in solids and liquids. That lets particles
    move freely within its space. When it is enclosed, pressure is
    forced onto its surroundings—just like how a balloon expands. It's
    all because of pressure. Examples of gases include oxygen, water
    vapor, clouds, helium, and things of the sort.

    PLASMA

    Plasma are like gases but differ because they are ionized which
    lets them carry electrical currents and generate magnetic fields.
    They are the most common form of matter. The universe, as far
    as our knowledge have shown, is made up of more than 99% of
    plasma! Examples are the sun, stars, lightning, and things of the
    sort.
    THE ROLE THAT ENERGY PLAYS
    IN THE CHANGE OF STATES OF MATTER
    Energy and temperature (heat) go together because they're basically the same thing.
    Energy is a very strong factor. With energy you can can break things apart. With energy
    you can even change the state of matter. How is it possible?

    CHANGING STATES AND COMPOSITION OF MATTER

    SOLIDS

    Through sublimation solids can change to gases. Take dry ice for example. When its
    force that keeps them close together is strong, it stays a solid. But when too much there
    is too much energy and there particles start moving, they lose their grasp. Particles start
    to loosen up and they soon become a gas.

    LIQUIDS

    Through evaporation liquids become a gas. Take lake waters for example. With the
    bright sun, some of that water will turn into water vapor—they evaporate. And what do
    you know? Water vapor is a gas!

    GASES

    Through condensation gases turn back into a liquid! An example can be a glass of cold
    water on a hot day. The water vapor from the warm air touches the cold glass and
    becomes, once again, a liquid.

    PLASMA

    Gases can become a plasma when they release electrons—which then produces more
    energy. That is called ionization. When they recombine, it's called recombination.
    KINETIC THEORY OF MATTER

    Energy, also temperature, is the main factor of this theory. Because of energy, matter can
    move and can change its state. Sublimation, evaporation, condensation, ionization,
    recombination, and many other processes can change matter because of their energy.
