Rounding Data When data is gathered and calculated, the final information presented tends to be rounded. On some occasions it may be necessary to round data, especially when rounding non-integer vales to integer values for simplicity and statistical representation. An example of this would be at the end of the calculations in sample weighting, the fractions you get are rounded to integers, since the data is based on physical objects which cannot have fractions, and so is considered extra for…

keen to learn how to incorporate chemistry into my daily life. Synopsis- The Disappearing Spoon starts off with an introduction in which Sam Kean narrates how he fell in love with the science of chemistry, because as a child he broke open mercury thermometers. Each of the…

Galileo Galilei was born February 15, 1564 in Pisa, Italy. He was a Tuscan (Italian) astronomer, physicist, mathematician, inventor, and philosopher and his father was a musician. His father had planned for him to study medicine, but he went to study mathematics. Galileo had many accomplishments / developments that change our world even till today. Galileo had many accomplishments that made him different from other people during the 15th century. He acquired his knowledge since his dad sent…

movement of the oceans water driven by the temperatures, waves and tides are constantly mixing the water, moving warmer and cooler water to deep and shallow levels. It would be extremely difficult to get an accurate temperature by simply using a thermometer, So scientists use many different methods to get the most accurate data. Since the early 1960’2 scientist have been able to measure the temperatures of the oceans from 300 to 2000 meters deep using a device they called the xpendable…

Throughout history conflicts between countries has been solved by war. One of the most famous wars in history, World War I, was a disastrous, life-changing event for millions of people. All Quiet on the Western Front, by Erich Maria Remarque, tells what war is like through the eyes of Paul Baumer. He experiences the hardship of war at the young age of nineteen. Him and his school friends, persuaded to go to battle by their school teacher, undergo stressful events no man of their age should have…

that were on this list included NASA’s COBE probe mapping the fiery aftermath of the Big Bang and confirming that chlorofluorocarbons were eating the stratospheric ozone. Other inventions that are here with the help of NASA include infrared ear thermometers, artificial limbs, anti-icing systems for airplanes, devices that safely destroy landmines, firefighter gear, and many…

The Ancient Greeks and Romans. There are many differences and similarities between the two empires, from their famous leaders throughout history, to their declines. It is interesting to study and go over what made up their Empires, the achievements that set them apart from others in history, and what each time period held for their people and their ways of living. We will be looking at and going over some of the main parts of their empires, from their famous leaders to the reason(s) for their…

Characteristics of the Four Elements The four Elements possess unique characteristics and their functions are related to these characteristics. These characteristics have been explained carefully, with ultimate simplicity; where accurate and deep meanings have been considered which will also been elaborated in future sections. Briefly, the four Elements include the following components: Fire Air Water Soil a) Fire: comes with Heat and Dryness. It is the lightest of all Elements b) Air: comes…

added to a 25-mL round-bottomed flask along with a stir bar. To dissolve the camphene, 3.0 mL of glacial acetic acid was added into the flask. The flask was fastened onto a ring stand and immersed in a water bath that was on top of a stir plate. A thermometer wire was placed in the water bath to monitor the temperature throughout the experiment. After the camphene dissolved, 0.50 mL of 8 M sulfuric acid (H2SO4) was added. To prepare for heating, a cork was placed upside down to cap the mixture…

Hydrogen Peroxide Decomposition Lab Report Objective: By utilising the catalyst of potassium iodide to trigger a decomposition reaction in hydrogen peroxide, how will fluctuation in temperatures will affect the decomposition rate? Hypothesis: Due to the decomposition effect of potassium iodide on hydrogen peroxide, the increased temperature applied will also increase the decomposition rate, because of the more occurrences of collisions which causes the more energy to be produced. Independent…
