Chemistry and Society

Chemistry plays a huge and important role in society; Society depends on the accuracy and precision of measurements for products sold by the retail industry, such as a gallon of gasoline, a bushel of corn, or a liter of bottled water. These measurements have to be precise and accurate when it this relates to how farmers sell their products such as wheat, corn, milk, peanuts, and cotton, by weight and or in a bulk sale. Like food products gasoline, water, oil, and several other liquid goods are sold in quantity and if the measurements are not accurately sold per gallon then the United States government will not retain a profit from the barrel of gasoline, water, oil, and several other liquid goods that are purchased from other countries. Accuracy and precision are two important factors to consider when taking data measurements. Both accuracy and precision reflect how close a measurement is to an actual value, but accuracy reflects how close a measurement is to a known or accepted value, while precision reflects how reproducible measurements are, even if they are far from the accepted value. But before scientist can delivery any of these measurements, they need to go through the scientific method. The scientific method is a process for experimentation that is used to explore observations and answer questions. Scientists use the scientific method to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to vary in a predictable way. There are a few steps to follow on the scientific method to get the results that they want, and they are: ask questions, do background research, construct a hypothesis, test the hypothesis by doing an experiment, analyze the data and draw a conclusion, and last, communicate the results. But not only scientist use the...
