Chemistry of fireworks essays

Chemistry sometimes referred to as the central science because it connects other sciences to each other, such as biology, astronomy, medicine, physics, geology and environmental science. Chemistry is everywhere in the world around us; It 's in the food we eat, water we drink, medicine we take, clothes we wear, air, even the body is made of chemicals. Chemical reactions occur when we breathe, eat, run, or lay down.

We are. In biology, we did a bottle ecosystem with partners, and the reason I remember it is because our crickets died fast, and I was really upset with my partner since I did all the work. In Chemistry 2, Mr. Garber always had a really small class and so he did a fireworks unit. As a big finale to the seniors graduating from that class, we make a homemade firework as a class and lit it on their last day in class.

Our firework was supposed to shot up. These low explosive pyrotechnic devices are primarily used for aesthetic or entertainment purposes. Fireworks come in various forms, including sparklers, firecrackers, basic fireworks, and ariel or display fireworks.

  • Those who watch firework displays find that those can be broken into smaller categories by four primary effects. These effects. In many cases, the examiner can visually interpret agglomerations of combined spheroidal and broken particles, layered particles and particles attached to other masses, and single particles that could never be mistaken as spheres. This element has contributed to chemistry enormously over the years. This is the history of Boron and how it has affected chemistry. Time before Boron was rough. Which is a substance made to clean pretty much everything in your home.

    Also Boric acid is an important compound. After black powder was discovered by the Chinese in the 9th Century, the relatively short history of fireworks began with this explosive chemical composition. Black powder is made up of potassium nitrate, sulfur, and charcoal KNO3 ; in the correct amounts, this combination has very explosive results. The use of black powder sprung forth the evolution of muskets, rockets, and fireworks. Although history has shown that the development of black powder muskets into modern day guns, artillery, and weapons.

    In this experiment fire is a big part of the black snake. But, it is also proven that your fire can be extinguished with baking soda. Also, sugar is used in this experiment. Fireworks are and have been an interesting thing for people of all generations and. We can get caught up in dream chasing, life, and children… Well, we forget how to connect with our lover.

    Every year, millions of dollars of damage is done by stray fireworks setting fire to property and there's also the distress that fireworks cause to pets to consider. That's why the sale and use of fireworks is restricted by law in many countries. If you're having anything to do with fireworks, be sure to read and follow all the safety instructions to the letter.

    Better still, why not leave handling fireworks to someone else? Go to a properly organized and supervised civic display and enjoy all the fun of the fireworks with none of the danger.

How do fireworks work? Working up from the bottom to the top: Stick "tail" : The first thing you notice is a long wooden or plastic stick protruding from the bottom that ensures the firework shoots in a straight line.

    Essay on fireworks A firework display Essay Example for Free - Sample words

    That's important for two reasons. First, so that fireworks go where you intend to and don't fly in a random direction, causing fires, property damage, or injuries. Second, because it helps display organizers to position firework effects with accuracy and precision. Some fireworks now have hinged plastic sticks so they can be sold in smaller and more compact boxes.

    Fuse : This is the part that starts the main part of the firework the charge burning and ignites other, smaller fuses that make the interesting, colorful parts of the firework the effects explode some time later. In a basic home firework, the main fuse consists of a piece of paper or fabric that you light with a match or cigarette lighter. In a complex public firework display, fuses are lit by electrical contacts known as wirebridge fuseheads.

    When the firework technician pushes a button, an electric current flows along a wire into the fusehead, making it burn briefly so it ignites the main fuse. Unlike manual ignition, electrical ignition can be done at a considerable distance, so it's much safer. It's usually made up of tightly packed, coarse explosive gunpowder also known as black powder. Traditionally, gunpowder used in fireworks was made of 75 percent potassium nitrate also called saltpeter mixed with 15 percent charcoal and 10 percent sulfur; modern fireworks sometimes use other mixtures such as sulfurless powder with extra potassium nitrate or other chemicals instead.

    Note that the charge simply sends the firework high into the air and clear of any spectators; it doesn't make the spectacular explosions you can actually see. Effect : This is the part of the firework that makes the amazing display once the firework is safely high in the air.

    A single firework will have either one effect or multiple effects, packed into separate compartments, firing off in sequence, ignited by a relatively slow-burning, time-delay fuse working its way upward and ignited by the main fuse. The firework illustrated here has three effects. Though essentially just explosives, the effects are quite different from the main charge. Each one is made up of more loosely packed, finer explosive material often fashioned into separate "stars," which make up the small, individual, colorful explosions from a larger firework.

    Depending on how each effect is made and packed, it can either create a single explosion of stars very quickly or shoot off a large number of mini fireworks in different directions, causing a series of smaller explosions in a breathtaking, predetermined sequence. Head : This is the general name for the top part of the firework containing the effect or effects collectively known as the payload—much like the load in a space rocket.

    Sometimes the head has a pointed "nose cone" to make the firework faster and more aerodynamic and improve the chance of it going in a straight line, though many fireworks simply have a blunt end. The science of fireworks Science teachers love fireworks because they teach you about chemistry and physics at the same time, in a very dynamic and colorful way! Chemistry of fireworks An exploding firework is essentially a number of chemical reactions happening simultaneously or in rapid sequence.

    Physics of fireworks The solid chemicals packed into the cardboard case don't simply rearrange themselves into other chemicals: some of the chemical energy locked inside them is converted into four other kinds of energy heat , light , sound , and the kinetic energy of movement. Types of fireworks Surprise and variety are the key to any good firework display: if all the fireworks were exactly the same, people would quickly get bored. A brief history of fireworks Who invented fireworks? Here's our quick history lesson!

    Chinese people believed to have made explosive rockets in the 6th century CE during the Sung dynasty —CE. Arabian world acquires rocket technology from the Chinese around 7th century.


    During the mid 13th century, English monk and pioneering scientist Roger Bacon experiments with the composition and manufacture of gunpowder. Rockets similar to fireworks are used during an invasion of China by Mongolian forces in The Mongols introduce firework technology to Europe and it spreads during the Middle Ages. Fireworks are produced in Italy around and spread to England, France, and other European countries the following century. November 5, Guy Fawkes — attempts to blow up the English houses of parliament with gunpowder buried in the cellar, giving rise to the popular British custom of huge public firework displays on November 5 each year.

    The custom of using fireworks for elaborate celebrations gains popularity in Europe in the 17th century.
