    Matter

    Uploaded by

    Matter can exist in four phases: solid, liquid, gas, or plasma. The phase depends on the amount of heat and pressure. Solids have a definite shape and volume, liquids flow but maintain their volume, and gases expand to fill their container and are easily compressed. Each state has distinct properties regarding density, compressibility, and ability to flow or change shape.

    MATTER

    Definition: - Any substance which has mass and occupies space. All
    physical objects are composed of matter, in the form of atoms, which are in turn composed of protons, neutrons, and electrons. Photons have no mass, so they are an example of something in physics is not comprised of matter. They are also not considered "objects" in the traditional sense, as they cannot exist in a stationary state

    Phases of Matter Matter can exist in various phases: solid, liquid, gas, or plasma. Most substances can transition between these phases based on the amount of heat the material absorbs (or loses).

    States of Matter: - State of Matter indicates how much heat is contained within the molecules of the substance. The more heat that is added, the more the molecules move and the harder it is for them to stay close together. The state of matter is dependent therefore upon both the temperature and pressure of a given substance. There are three states of Matter: Solid Liquid Gas

    Solid: -A substance having a definite shape and volume; one that is neither liquid nor gaseous.

    Examples: Ice Wood Stone Brick

    Liquid: - The state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility.

    Examples: Water Milk Fruit Juice Petrol

    Gas: - The state of matter distinguished from the solid and liquid states by relatively low density and viscosity, relatively great expansion and contraction with changes in pressure and temperature, the ability to diffuse readily, and the spontaneous tendency to become distributed uniformly throughout any container.

    Examples: Air dioxide

    Oxygen

    Hydrogen

    Carbon

    Properties
    Properties of Solids Solids have a fixed shape and a fixed volume. Solids cannot be compressed much. Solids have high densities. They are heavy. Solids do not fill their container completely. Solids do not flow.

    This brick is a solid. A solid has a define volume.

    Properties of Liquids Liquids have a fixed volume but they have no fixed shape. Liquids take the shape of the vessel in which they are placed. Like solids, liquids cannot be compressed much. Liquids have moderate to high densities. They are usually less dense than solids. Liquids do not fill their container completely. Liquids generally flow easily.

    This orange juice is liquid. A liquid flows easily. It has a definite volume bur no definite shape. The shape of a liquid depends on the shape of the container.

    Properties of Gases Gases have neither a fixed shape nor a fixed volume. Gases acquire the shape and the volume of the vessel in which they are kept. Gases can be compressed easily (into s small volume). Gases have very low densities. They are very, very light. Gases fill their container completely. Gases flow easily.

    The balloon on the right is filled with a gas (air). A gas has neither a definite volume nor a

    definite shape. It completely fills its container. A gas is much lighter than the same volume of solid or liquid.
