Accuracy and Precision Essay

Chemistry is a vibrant part of society.

When experiencing some of life’s simplest of pleasures, there is usually a process that has undergone different aspects of what a chemist studies every day. In the text for this course, the example of experiencing even a simple sunset can be related to chemistry. “Molecules in the air interact with light from the sun, scattering away the blue and green light and leaving a red and orange light to create the colors. ” Personally, it was very surprising to me to find out that out of all the sunrises I have been blessed to witness, I have never took the time to understand the process behind its beauty.The study of chemistry starts with understanding accuracy and precision.

Accuracy involves a true value. Being accurate involves no estimated figures but those instead that are not questionable. By using accuracy in chemistry, the results will have less of a chance of producing error. In society, accuracy is used in places such as the lumber yard and grocery store every day. When building homes and structures, contractors rely on the sizes of the wood purchased from lumber yards and also the measurements of lumber that is cut prior to building.Strict specifications that are not followed could result in damage to the basic foundation and frames which the home or structure belongs by causing undo stress on support beams.

In the grocery store, prices on produce and meat are based on weights. If the prices are estimated versus being accurate, the company loses money by not meeting above cost that was spent on purchasing produce and there will be no revenue. Being accurate is very different from being precise. Precise involves an estimate or how close of a range you are to something.For example, there is precisely four feet from where I am sitting to the door. This means that I am estimating based on the size of my feet. The measurement is not something that can reliable because if I measured it with a tool such as a measuring tape, it could possibly be shorter or longer.

Stated something is precise leaves question as to whether or not something is valid. Chemistry uses accuracy more so than precision because it studies the “properties and behavior of chemicals, by helping us understand the molecules that compose them.In my daily routine, I come in contact with needing to be accurate. Working in the hardware business, there are customers that rely on me to be accurate. Every day, when assisting customers, I have to be knowledgeable of sizes, weights, and chemical components that don’t mix well with one another. Especially when working with chemicals, it is important to educate our customers on what surfaces can be damaged by use of certain products and what alternatives are available to use that will render more appropriate results.Three types of measurement that I rely on daily are the use of feet, pounds, and some metric measurements as well. All pipe, black and galvanized, is measured in feet.

Black pipe is used when doing gas and galvanized is used for water. Schedule forty, thin wall, S & D and PVC pipe are all different widths and lengths and can be used for water and waste. The thickness and durability of these products are important because they have to withstand a lot of pressure. Fittings have to be accurate in fit and size.

All loose nails, seed, and kerosene are sold by the pound. Nail are of different varieties and used on different surfaces. Some screws and nails are by sizes that are in metric measurements. Without the use of accuracy in my daily job, household projects, repairs, and building structures would be faulty. Chemistry and accuracy are a vital part of society.
