What Is Matter? By: CristalMares

Matter is a physical a distinct mind or spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.

The two different types of matter is pure substance and mixture.

Pure substances is a sample of matter with both definite and constant composition with distinct properties.

Examples of pure substances include tin,sulfur,diamond, water, pure, sugar (sucrose), table salt (sodium chloride) and baking soda (sodium bicarbonate)..... All elements are pure substance. Water, sugar, salt and baking soda are pure substance which are chemical compounds.

Element

Elements, Mixtures and Compounds. Chemistry is the study of physical matter, which is classified in many ways,such as state matter (gas,liquid or solid), chemical form (element, mixture, or compound),chemical structure (atoms of molecules,etc.) and so on.

Examples of elements include oxygen, hydrogen, sodium,chlorine,lead,iron. Examples of compounds include water ( or hydrogen oxide ) H2O ; and Sodium Chlorine , NaCl. H is the symbol for hydrogen , the number 2 as used here means there are 2 atoms of the element hydrogen in every molecule of the compound water.

Compound

Compound is a thing that is composed of two or more separate elements; a mixture.

There are many types of compound, like carbon dioxide (carbon and oxygen), common salt (sodium, chlorine), marble ( calcium, carbon, oxygen), copper (II) sulphate (copper, sulfur, oxygen) and hydrogen chloride (chlorine and hydrogen). Compound is made up of two or more elements. Examples include water.

Mixture

Mixture is a substance made by mixing other substances together.

Examples include ice cubes in a drink, sand and water, and salt and oil. Liquid that are immiscible form heterogeneous mixtures. A good example is a mixture of oil and water. Chemical solutions are usually homogeneous mixtures.

Homogeneous

A mixture which has uniform composition and properties throughout. For example, air is a homogeneous mixture of gases. A teaspoonful of table salt stirred into a glass of water also makes a homogeneous mixture.

Examples of homogeneous, often contains dissolved minerals and gases, but these are dissolved throughout the water. Tap water and rain water are both homogeneous, even though they may have different levels of dissolved minerals and gases.

Solutions

Many homogeneous mixtures are commonly referred to as solutions

Example: Sugar solution when the entire solution become colorless, Salt water solution, Air with no clouds, Diluted wine, Vinegar solution.

Heterogeneous

Heterogeneous Mixtures is a combination of two or more pure substances in which the original substances retain their chemical properties, In some mixtures, the initial substances cannot be detected after they have been mixed.

For example, salt and pepper, chocolate chip cookies. or Twix candy bar,..... are all examples of heterogeneous mixtures, where substances are not mixed on a molecular level. Soda is a heterogeneous mixture (liquid solution) of H2O, C6H12O6, and few others substances.

Suspension

In chemistry, a suspension is a heterogenous mixture containing solid particles that are suffcienty large for sedimentation. Usually they must be larger than one micrometer.......This distinguish a suspension from colloid, in which the suspension particles are smaller and don' t settle.

Particles will settle to the bottom in a suspended solution. Emulsions are a type of suspension, where two imiscible liquids are mixed together. Examples of suspended solutions include salt water, sand in water, and muddy water.

Colloid

a homogeneous, noncrystalline substance consisting of large molecules or ultra microscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

Types of colloids. Colloids are common in everyday life. Some examples include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper. Every colloid consists of two parts: colloidal particles and the dispersing medium.
