Chemistry is not used only in a lab environment, but it is used for every aspect of life. One way to look into a more in-depth view of chemistry is to apply it to a hobby, or something that may personally affect your everyday life. One of the biggest parts of my life and my main hobby is flying. Ever since I was little, I have always wanted to become a pilot. I am currently working towards my private pilot’s license and I am also attending the U.S. Air Force Academy starting in June to study aeronautical engineering. Since flying is such a large aspect of my life and is important to me, I wanted to break it down into an aspect of chemistry. I chose this topic because flying is very important to me and it will continue to be a large part of my life as it will end up being my career in the Air Force. Not only will researching the topic of aviation fuel help me to become a more knowledgeable pilot, but it will also help me to understand more about chemistry and expand on the concepts we have learned this semester. Chemistry is extremely important to planes and pilots. One of the most obvious aspects of flying that deals directly with chemistry is fuel. Without fuel, aircraft would not be able to run. The molecular formula of fuel and the combustion of fuel are just some parts that play into how fuel makes an aircraft run.
When looking at the fuel used in aviation, there are many aspects to look at. First of all, there are multiple different types of fuel used in aviation because of the different types of aircraft. Comparing the fuels can help explain why different planes use different fuels. Military, civilian, and airline aircraft all use different types of fuel. The different military jet fuel grades include JP-4, JP-8, and JP-5...

...ine engine on the larger aircraft. The different engines provide different hazards, so they must be compromised with different grades of fuel. The chemical properties of these fuels is what makes them so different. One of the most important aspects in choosing which fuel goes in which time of plane is the type of engine and also the type of climate it will be flying in. This is important because the larger aircraft are flying at higher altitudes which means lower temperatures, so it is necessary to have a fuel with a lower freezing point. Taking a specific subject such as aviation fuel can help you look at the world with a microscopic view. Every day that I fly I have to deal with fuel, learning the chemistry behind the fuel was a great lesson because I was able to use and apply what I have learned in chemistry class to something in which I am very passionate about.
The Cartoon Guide to Chemistry by Larry Gonick and Craig Criddle is a non-fiction book that utilizes visual images and cartoons to cover the basics and intricacies of Chemistry. It consists of two-hundred and fifty-six pages and was published by Collins Reference on May 3, 2005. It covers topics such as chemicals reactions, solutions, acid basis, and chemical thermodynamics in unique fashion that makes chemistry fun and easy to learn as well as understand. The book has no consistent build up or story to it. It simply moves from chemistry subject A to chemistry subject B, explaining the various components that make up the subject of chemistry.
Did you know that you can receive a maximum of a $7,500 tax credit for just owning an electric or hybrid vehicle? The United States government values citizens that buy fuel efficient vehicles because it gets the United States one step closer to not buying outsourced oil (Jones par.14). Hybrid vehicles are vehicles that are mostly powered by gasoline, but switch over to electric at stop signs or at coasting speeds. Electric cars are cars that are solely powered by electric from start up to shut down (Motavalli par. 6). Most cars and trucks on the road today are powered by gasoline or diesel engines, which are expensive to operate, bad for the environment, and use resources that are non renewable. To achieve better fuel economy, lower operation cost, reduce the pollution on the environment, and operate vehicles with renewable resources, this world needs to take a better look at using alternative fuels to power vehicles. Alternative fuels for motor vehicles are better for the environment, are renewable resource, and are cheaper for consumers.

Sitting in AP Chemistry lab class, thinking about how much I didn't fit in with all the brilliant overachievers, I began to wonder why I took the course. While I knew it was because I have a passion for chemistry, I didn't know what exactly entices me about the subject. Moments later, I found my answer; I love experimenting. Reading textbooks and listening to lectures are definitely informative, but they aren't the only ways to learn. Learning through experience and physical results is the most interesting and fun way to understand topics. Reading about chemical reactions and actually performing and seeing results is another, which is why the “volcanic eruption” project is so popular. Instead of trusting everything textbooks say, people can
In Frederica P. Perera’s article ‘Multiple Threats to Child Health from Fossil Fuel Combustion: Impacts of Air Pollution and Climate Change’ she uses factual data to discuss the effects air pollution brings to adolescents. The importance of this rising issue has allowed her to bring validity to the argument. Despite this, her knowledge and ability to document her evidence, has caused her to stray away from her own thoughts which was not beneficial in connecting with her readers.
Some people think of chemistry as boring. Others believe it to be boring. Even some consider it both. So whenever a job with the title “chemist”, a lot of people just skip over it without even seeing what it really is. There is one job, however, that can make these naysayers rethink their opinions. That would be a food chemist.
For a rocket to fly in the air it needs thrust and thrust has to use fuel. There are different types of fuel a rocket can use, there is solid and liquid fuel. They are known to be the most used and easy to use. Solid fuel never stops burning, once it starts the burning does not stop. Solid fuel can only burn for two minutes and can easily evaporate at normal temperatures. Since it can’t stop burning and is easily evaporated it is used in missiles, commercial rocket and wood stoves. Liquid fuel can be used on space travels and missions. This type of fuel is best used for space travel for the reason that it is long lasting. Liquid fuel other than the solid fuel can
We will start with the fuel tank. A fuel tank comes in many different sizes depending on how much space is available. Most cars and trucks have only one tank but some trucks have two. Fuel tanks can be made of 3 different things. These are pressed corrosion-resistant steel, aluminum, or molded reinforced polyethylene plastic. The fuel tank has internal baffles or surge plates to prevent the fuel from sloshing back and forth. If you hear splashing in the tank on acceleration or deceleration, this means that the baffles could be broken. All tanks have a fuel filler pipe, a fuel outlet line to the engine and a vent system. All catalytic converter cars are equipped with a filler pipe restrictor so that leaded fuel, which is dispensed from a thicker nozzle, cannot be introduced into the fuel system. All modern fuel tanks include devices that prevent vapors from leaving the tank. All fuel tank designs provide some control of fuel height when the tank is filled. This is achieved by using vent lings within the filler tube or tank. With this design only 90% of the tank is ever full, leaving 10% for expansion. Some vehicles have a over filling limiting valve to prevent overfilling of the tank.
The link between the number of carbon atoms in a fuel with the amount of energy it releases
Nurses monitor vital signs, administer medication and insert IV’s. It is extremely important that they know how to give the correct dosage of medication to their patients because the wrong dosage could harm the patient. Chemistry gives nurses the knowledge about compounds like medicine. It teaches them what medications are made of and what they will do to the patient when it is administered. Understanding chemistry will allow nurses to know why medications within the same classification or similar names do not work the same.
Though many people fail to realize it, chemistry is a subject essential to everyday life, due to the fact that it is the branch of science that deals with the identification of the substances of which matter is composed. But what we must understand is that everything in the universe is composed of matter, hence chemistry is necessary in learning more about the world and universe that we live in. There are many careers and fields affiliated with chemistry that people pursue to learn more about the composition of the universe, but for now, let us examine the logistics of three of these careers. These three careers involving chemistry are geochemistry, environmental chemistry, and chemical engineering.
From the unit of chemistry in grade ten science, the students have learned many things from different types of elements in the chart all the way to how each element impacts the daily life each student or even adult lives in. Some of the things I as a student have learned include how to draw the different elements in a bohr rutherford diagram, balancing chemical equations, types of chemical reactions, and even information about the different types of acids and bases. Although there were many other things in the unit, these four definately helped me learn about chemistry in a more in-depth way, as well as teaching me something very new since these were some things a few of the students had never done in the previous years. Learning this in the classroom has really opened my eyes to the world in which we live in today, many times I leave the house on a cold day and as I look upon the cold water becoming ice or even the snow falling down, I know how it is happening, why it is happening, and I can even picture the molecules solidifying as we had seen in class with many different diagrams.
Throughout my school career I have always loved chemistry. In Chemistry there was always a sense that there was more, there was always something new and exciting to be discovered and theories to be proven (or even disproven). Chemistry was the main subject with a real practical aspect to it during school and it is this, along with my genuine fascination with the subject, which fuels my desire to study it further.
The growing relevance of Chemical Engineering in today’s world, from energy & oil industries to pharmaceuticals & biotechnology, and a keen desire for applying this knowledge in interrelated spheres motivates me to pursue a Master’s degree in this field. My interest in science goes back to the time when I was in school. We had a young and enthusiastic teacher who took us on field trips and visits to science fairs and museums. This nascent interest has only burgeoned through my years in school and high school, as I have learnt more about the subject. In the long run, I see myself as a part of a leading research group, either as a faculty member or in the R&D department of an organisation contributing my bit to the field of Chemical Engineering. As a research scientist, I hope to make a difference in this field and learn more through the innovative challenges.
