Macroscopic Level Lab Report
At the macroscopic level when a firework goes off the effects of molecules interacting can be observed through the light being produced. I expect the firework to travel to a high distance vertically in the air. I expect the firework to start in a tight ball. As it travels the tight ball (of molecules) will expand in its perimeter causing the firework to combust, making a very loud bang. I’m sure that heat radiates as a outcome of this interaction, though it wouldn’t be smart to get close enough to feel the heat. Also, I expect the combusting to give of a burning smell, similar to an explosive. At the molecular-level when a firework goes off molecules will begin to exchange electrons due to increasing levels of temperature (must be ignited
Ccto10 Unit 2 Lab Report
335 Words | 2 PagesK.D.A. Saboia et al. , (2007) have been prepared the Bi4Ti3O12–CaCu3Ti4O12 {[BIT(X)–CCTO(100-X)]} composite powders through solid state reaction method and calcined in the range of 900 to 1020 ºC for 12 h. The as-prepared powders have modified in the form of thick film onto alumina ceramic substrate by utilizing screen printing. At 100 Hz, the value of dielectric constant (κ) of CCTO100 and BIT100 is 316.61 and 53.64 respectively. Conversely, the composite with X=20 % shows an unexpected dielectric constant of 409.71, which is around 20% higher in comparison with the CCTO.
Crucibles Book Report
200 Words | 1 PagesIn a Beacon School, located in NYC, two-tenth - graders were seriously injured, leaving a boy with critical burns and another student with fewer server burns from her neck, head, and arm. Anna Peole, chemistry teacher was showing a “demonstration of rainbow flames” which will result burning of 4 different kinds of nitrates in separate crucibles in the classroom. However, the unstable amount of methyl alcohol hazes around the chemistry lab and explodes across the lab table surrounding Alonzo Yanes, a sophomore at the Beacon School. Alonzo Yanes was standing a few feet away from the lab table, where the crucibles were.
Hastings Point Lab Report
1610 Words | 7 PagesIntroduction For two days, on the 14th and 15th of April, a field excursion to Hastings Point, New South Wales was conducted. At Hastings Point, topography, abiotic factors and organism distribution were measured and recorded, with the aim of drawing links between the abiotic factors of two ecosystems (rocky shore and sand dunes), the organisms which live in them, and the adaptations they have developed to cope with these conditions. Within these two ecosystems, multiple zones were identified and recorded, and this report also aims to identify the factors and organisms associated with each zone. Lastly, using data and observations from the past, predictions for the future of the rock pool ecosystem were made.
Gun Fire Research Paper
721 Words | 3 PagesHave you ever wondered what happens when a gun fires? I have been hunting for almost all my life and I have started to wonder about this. For my science fair project I 'm going to find the reaction of explosions. I also find this interesting because I want to make guns someday. I believe that understanding the Chemistry and Physics of explosions may help me to find the answer to my question.
Lab Report
1244 Words | 5 PagesST Report In the experiment, the problem was the contaminants that were affecting the quality of the water samples. To fix this issue, three scientists had to determine the contaminants that were present in the samples. One sample was from the school sink and the second sample was from an unknown source. The scientists conducted many tests to figure out what pollutants were present in the water.
How Gunpowder Changed Warfare
946 Words | 4 PagesGunpowder is made up of saltpeter- a common name for the oxidizing agent potassium nitrate- sulfur and charcoal (Heather Whipps, 2008). When the Chinese scientists first mixed the ingredients together it resulted in smoke and flames, causing their hands and faces to burn (Heather Whipps, 2008). One of the first
The Perfect Match Rhetorical Analysis
1401 Words | 6 PagesSince they are drawn to each other so intensely, they are not paying attention to what they are holding. Look at the amount of the fireworks the woman has. Also, look how powerful the blow torch is. If they were lit up at the same time, it’s more than enough to blow up the whole area that they are standing at. The fire and the fuse are so close to each other that if they get any closer, there is no doubt that there will be “Chaos.”
Battle Of Verdun World War 1 Essay
1232 Words | 5 PagesA flamethrower is a device designed to project flames and massive clouds of smoke in a controlled manner during wars. It was mostly used in battlefields, fortifications, bunkers and any other closed or shielding location. It was used because it can jet out flames up to 20 yards away from where the person controlling it is standing. It was also created to be carried and used by a single soldier. The device was first used on February 26, 1915 by the German 3rd pioneer regiment.
Pyro Board Research Paper
612 Words | 3 PagesThe flames create a visual demonstration of the sound wave as it travels through the standing wave. On account of displacement, nodes correspond to pressure antinodes, and displacement antinodes correspond to pressure nodes. Causing the flames to react. Notwithstanding other outside factors.
Substrate Concentration Lab Report
181 Words | 1 PagesHypothesis: Increasing substrate concentration will increase the initial reaction rate until it stops increasing and flattens out. Independent Variable: Substrate concentration Dependent Variable: The substrate itself, 1.0% Hydrogen Peroxide How Dependent Variable will be Measured: Hydrogen Peroxide will be used in every experiment, just with different test tubes. The amount of Hydrogen Peroxide in the mixing table is the amount that will be added to each test tube.
Science Behind Gunpowder
537 Words | 3 PagesFurthermore, the explosion of the firework isn’t the only occasion for the sound. For example, when you shoot certain rockets you’ll here the whistling sound as the firework goes up and then a bang as it explodes.
Sputnik Research Paper
227 Words | 1 PagesAs the step rocket burned out and fell off in the sky, the firework would continue going much farther than it would have normally gone. This technology is still used in rockets today, and is in part responsible for our vast improvement in rocket technology. According to nasa.gov, in the 17th century, Isaac newton created three laws of motion. These collectively explained how rockets could move in space, and how they could one day be used for space
Macromolecules Lab Report
1486 Words | 6 PagesIntroduction The purpose of this lab is to use control variables to help identify different macromolecules. Biological systems are made up of these four major macromolecules: carbohydrates, lipids, proteins and nucleic acids. Carbohydrates are sugar molecules (monosaccharides, disaccharides, and polysaccharides) which make them the most abundant macromolecule on the earth. Lipids (oils and fats, phospholipids and steroids) are insoluble in water and perform many functions such as energy source, essential nutrients, hormones and insulators (Lehman, 1955).
Oak Trees Research Paper
1334 Words | 6 PagesFires are very dangerous. Fire is not matter, and it is matter in the process of transformation. Fire needs oxygen, heat, and fuel present at one time to form. A fire starts when a fuel such as wood heats to a high temperature. It is usually caused by focused light or friction.
Fire Cause Determination Essay
804 Words | 4 PagesDifference Between Origin and Fire Cause Determination. Today in this paper I am going to write about the major differences between the origin of a fire or explosion, and the cause and determination of a fire. I will first separate the two subjects, then give a few examples of clear differences between them, give a partial scenario, and a conclusion to hopefully give a clear meaning to both terms. Now without further due, I would like to present my thoughts and findings about determining the fire’s origin.
