In today's society it is very rare to find someone who does not own a cell phone. There are ten-year-olds running around with iPhones. Cell phones have become such an important part of society. They have led the way with the advancements made in technology to allow these phones to do more than you would think possible. Now we don't just use them to contact people, we use them for social media, to take photos, browse the web and get information with the touch of our fingers. It's crazy to think that cell phones once didn't exist. Without the use of chemistry we would not have the cell phones we use today. Chemistry is defined by the Holt textbook Modern Chemistry as the scientific study of the composition, structure, and properties of matter and the changes that matter undergoes. Chemistry is responsible for the batteries found in all our cell phones. Without these batteries there would be no phone. The battery is the main power source of the phone and without it the phone would not work. Chemistry is used in our daily lives in more ways than we might think. One way we use chemistry is in our cell phone batteries. They are solely responsible for actually turning on and powering the phone to work. Most cell phones are powered by a rechargeable lithium-ion battery. Lithium-ion batteries are commonly used in digital cameras and even electric cars. These batteries are made of lithium cobalt cathode and carbon anode. For as long as I have lived there has always been some form of cell phone. Before the invention of cell phones I imagine the world was much more mysterious than the world. Now we can find all the information on our phones. We have phone addicts who have to have their own phone... middle of paper... and we will rely solely on our phones for everything. This is what the world is getting closer to as cell phones continue to become more and more advanced. We will be so absorbed in our cell phones that we will hardly notice others around us. Cell phones are great in many ways and have very few drawbacks. Without chemistry there would be no cell phone. We would be missing many of the essential parts to make a cell phone without the known knowledge of chemistry. As we learn more about chemistry, we can focus more on the advancements of cell phones and technology in general. Things have changed a lot since the first cell phone and will continue to rapidly change the face of the cell phone. Life with a cell phone has given us a lot of freedom, made communication easier and has greatly influenced the daily lives of people who own one.
