Answer:

Art and music are basic human functions. Humankind and art cannot function without one another. We have the burning desire to create, whatever it may be and however tiny or grand. The interaction with sound is unavoidable, either to make it or take pleasure in it. People have always found music significant in their lives, whether for enjoyment in listening, the emotional response, performing, or creating. This is no different for classical music or contemporary concert music. Both musics have immense worth for our society; however, the problem we all know in this field is that this music is little known and hence underappreciated. As a musician and artist it is my responsibility that others can learn to enjoy the art for which I have utter passion.

It goes without saying that in mainstream American culture, classical or concert music is not a huge part of people's lives. There are still stigmas that contribute to this, as well as the practices of the government in the last two decades (declining music education in schools on the local level, resistance to increased NEA funding and less visibility of the arts on the national level; let us hope that the Obama administration can start to reverse these trends). Many people may still believe that classical music is for the rich, older, and the well-educated. Others may feel awkward about going to classical music events because they feel as if they need to act and dress a certain way in order to enter the concert or recital hall. Even more, the pretentiousness and elitism that some artists exhibit is amplified by some television shows, commercials, plays, books, by people of influence and even themselves, which distance musicians from mainstream society. While some of this is true, as with nearly any stereotype, it is not entirely true. With the impression that concert music has on society, the majority decide that it is not "for them" simply because they believe it has no relevance or worth to their lives. This is further compounded by the past government's lack of interest in promoting and supporting the arts, whether it is to fund arts organizations or arts education. Now, the current government give us hope and we have seen evidence of its commitment; but most importantly our American society needs to believe that everyone can find worth and enjoyment in classical/concert music.

Introduction

A mixture is a combination of two or more substances that are not chemically united to each other. Mixtures can be classified into two types: homogeneous mixture and heterogeneous mixture. A homogeneous mixture is one whose composition is uniform throughout the mixture. It is the type of mixture where the composition is constant throughout or the components that make up the mixture are distributed uniformly.

What is a Homogeneous Mixture?

A homogeneous mixture is a gaseous, liquid or solid mixture that has the same proportions of its components throughout a given sample. It is uniform in composition throughout. There is only one phase of matter observed in a homogeneous mixture.

Examples of Homogeneous Mixture

Air

Sugar water

Rainwater

Vinegar

Dishwashing detergent

Steel

Cup of Coffee

Mouthwash

Detergent

Cologne

Jello gelatin

Some Important Terms

Suspensions

Why do painters always mix the paint before using it? It is because the paint is a kind of suspension. The particles here are greater than 5 x 10-7 m in size, which means that you can see the particles with the naked eye. Fine sand mixed in water is another example of a suspension. Over the period of time, the particles tend to settle (or float) and have to be mixed again to restore the suspended state.

Solutions

Salt or sugar dissolved in water is an example of a solution. The particles are less than 2 x 10-9 m in size. They are so small that you cannot distinguish between the solute (the thing being dissolved) and the solvent (the thing that dissolves the solute).

Colloids

Colloids are the ones whose particle sizes range from 2 x 10-9 m to 5 x 10-7 m. Here the particles are small enough that they remain suspended. The intermolecular forces are strong enough to overcome the nature of particles to settle or float, owing to their small sizes. A few examples are given below which will help you better understand the nature of colloids.

Types of Colloids:

Depending on the dispersion medium (solid, liquid, gas), colloids themselves can be further classified. Here is a table to help you out.

Phase of Dispersion Medium of Dispersion Colloid Type Example

Solid Solid Solid Sol Gemstones, Pearls

Liquid Solid Gel Cheese, Jellies, Jam

Gas Solid Solid Sol Pumice Stone

Solid Liquid Sols Gum, Cell Fluids

Liquid Liquid Emulsion Milk

Gas Liquid Foam Froth, Whipped Cream

Solid Gas Aerosol Smoke

Liquid Gas Aerosol Fog, CloudsSwipe left
