material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena.
The basic building blocks of matter are atoms. All matter shares certain fundamental properties. Every physical entity has gravitation, the property by which it attracts every other entity. Another inherent and permanent property of matter is inertia, which causes a body to resist any change in its condition of rest or its motion. The mass of a body is a measure of its inertia, though it is commonly taken as a measure of the amount of material contained in the body.
Matter in bulk may have several states, the most familiar of which are the gaseous, liquid, and solid states. Less clearly definable but also referred to as states of matter are plasma, clusters, and amorphous conditions such as the glassy state. Each such state exhibits properties that distinguish it from the others. Moreover, these general states can be subdivided into groups according to particular types of properties. Solids, for example, may be divided into metallic, ionic, covalent, or molecular based on the kinds of bonds that hold together the constituent atoms.
According to Albert Einstein's special theory of relativity, matter (as mass) and energy are equivalent. Accordingly, matter can be converted into energy and energy into matter. The transformation of matter into energy, for instance, results during nuclear fission, which involves the splitting of a nucleus of uranium or another heavy element into two fragments of almost equal mass.

Anything which occupies space and has mass is known as matter. Properties describe matter. A block of wood, milk, and air all have properties. All the material on earth is in three states-solid, liquid, and gas. The "state" of the matter refers to the group of matter with the same properties. In other words, you group the objects together according to their properties. types: there are three types of states of matter solid, liquid gaseous state Properties and Examples: Solids The wood block is solid. A solid has a certain size and shape. The wood block does not change size or shape. Other examples of solids are the computer, the desk, and the floor. Liquids Milk is a liquid. Milk is liquid matter. It has a size or volume. Volume means it takes up space. But milk doesn't have a definite shape. It takes the shape of its container. Liquids can flow, be poured, and spilled. Did you ever spill juice? Did you notice how the liquid goes everywhere and you have to hurry and wipe it up? The liquid is taking the shape of the floor and the floor is expansive limitless boundary (until it hits the wall). You can't spill a wooden block. You can drop it and it still has the same shape. Gases Run in place very fast for a minute. Do you notice how hard you are breathing? What you are breathing is oxygen? You need oxygen to live. That's why you can only hold your breath for a certain amount of time. You can't see oxygen. It's invisible. It is a gas. A gas is matter that has no shape or size of its own. Gases have no color.

PROPERTIES OF MATTER :
1. A Substance may be identified by certain Qualities, or Traits. A QUALITY OR TRAIT THAT IDENTIFIES A SUBSTANCE IS CALLED A PROPERTY.
2. The property of a substance stays the SAME even if the Volume changes.
3. COLOR, MASS, SMALL, DENSITY, AND COMPOSITION ARE ALL EXAMPLES OF PROPERTIES THAT CAN HELP SCIENTIST IDENTIFY SUBSTANCES.
4. A PROPERTY THAT ALWAYS STAYS THE SAME IS CALLED A CHARACTERISTIC PROPERTY BECAUSE IT IS A CHARACTERISTIC OF A PARTICULAR KIND OF MATTER.
5. EVERY SUBSTANCE HAS TWO KINDS OF PROPERTIES - PHYSICAL PROPERTIES AND CHEMICAL PROPERTIES.
6. A PHSICAL PROPERTY is a property of matter that can be OBSERVED or MEASURED WITHOUT CHANGING the composition of the substance.
7. Physical properties are often used to identify substances.
8. SOME PHYSICAL PROPERTIES OF MATTER:
A. BIOLING POINT - The temperature at which a substance changes from a liquid to a gas.
B. CONDENSATION POINT - The temperature at which a substance changes from a gas to liquid; same temperature as boiling point.
C. DENSITY - The mass of a specific volume of substance.
D. FREEZING POINT - The temperature at which a substance changes from a liquid to a solid; same temperature as melting point.
E. MELTING POINT - The temperature at which a substance changes from a solid to a liquid.
F. RESISTANCE - The opposition of a substance has to the flow of electric current.
G. SOLUBILITY - The degree to which a substance will dissolve in a given amount of another substance, such as water.
9. In many cases, Physical Properties depend not only on the substance itself, but also on the environment of the substance.

occupies space,it has weight,it is indestructible(mass wise),it offers resistance,it will move when it has an external force acting on it, It has inertia,it has elasticity,it has adhesion,it has porosity,it is compressible,it is ductile.It can be drawn in to wires.It has surface tension,It has viscosity, It has density, It has atomic structure, It consists of atoms and molecules, It could be acidic or basic, It could be solid, liquid or gas, It could have magnetic properties,It is a conductor or insulator of heat, It could be conductor OR insulator of electricity,

Well, matter can neither be created nor destroyed, it takes up volume, it comes in three forms(solid, liquid, gas)...and that's about all I can think of off the top of my head.
