What is Matter? BY: Logan harper

What is Matter? Matter is anything that has a mass and takes up space.

An example of matter is an apple, a person, a table, air, water, a computer, paper, and iron.

A pure substance is a sample of matter with both definite and constant composition with distinct chemical properties.

An element is a type of matter composed of atoms that all have the same positive charge on their nuclei. An example of an element is hydrogen, helium, lithium and others.

A compound is a substance formed when two or more chemical elements are chemically bonded together. An example is pure water, is a compound made from two elements- hydrogen and oxygen.

Mixture-A mixture is a combination of two or more pure substances in which each pure substance retains its individual chemical properties.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

Definition of Homogeneous Mixture: 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.

A solution is a homogeneous mixture of two or more substances. A solution may exist in any phase. A solution consists of a solute and a solvent. The solute is the substance that is dissolved.Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water.

Heterogeneous Definition: A heterogeneous mixtures is one which has a non-uniform composition.

Examples: A mixture of sand and water is heterogenous. Concrete is heterogeneous.

A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase some time after their introduction.Sometimes, in the right light, you will be able to see particles of dust floating in a room. Eventually the dust will settle on the floor and on furniture, and the room will need to be cleaned. Dust in air is a suspension.

If you go to a beach and mix sand and water in a bucket you will form a suspension. Given time, the sand will settle on the bottom of the bucket to leave clear water.

Milk is an emulsified colloid of liquid butterfat globules dispersed within a water-based solution. A colloid, in chemistry, is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance.Colloids are mixtures whose particles are larger than the size of a molecule but smaller than particles that can be seen with the naked eye. Colloids are one of three major types of mixtures, the other two being solutions and suspensions. The three kinds of mixtures are distinguished by the size of the particles that make them up. The particles in a solution are about the size of molecules, approximately 1 nanometer (1 billionth of a meter) in diameter.
