MATTER IS ANYTHING THAT OCCUPIES SPACE



Matter is everything around you. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space. If you are new to the idea of mass, it is the amount of stuff in an object. We talk about the difference between mass and weight in another section. Matter is sometimes related to light and electromagnetic radiation.

PHYSICAL CHANGES

 A physical change is a change in which no new substances are formed. Physical changes affect the form of a chemical substance, but not its chemical composition. Mixtures can be separated into their parts by physical methods, such as spinning in a centrifuge. but can not usually be used to separate compounds into chemical elements or simpler compounds.

Most physical changes are reversible. Examples: changes of shape, changes of states, passing electricity through a copper wire. Some physical changes are melting, freezing, boiling.





CHEMICAL CHANGES

We say there us a chemical change in a matter when the internal make-up (molecules) of the object changes. Unlike a physical change, chemical changes cannot be reversed. Changes that cannot be reversed are called Non-reversible Change.
There are usually one or more new substances formed or created from that change. You can tell there is chemical change when it produces a gas, light, smell, fire (heat) or color change. A chemical change may also be accompanied by the formation of a solid in the form of a precipitate, and in some cases, accompanied by a gain or loss of energy.
A good example is the change that occurs when you fry an egg:

SEPARATING MIXTURE
The different substances in mixtures are usually easily separated from one another. The method you use depends upon the type of mixture you have.
