The first official cannon were made in the late 13th century. Chinese army used bamboo lead to severe burn due to sparks when they ignite gunpowder so the evolution on cannons was much needed and to the people who were operating the but after realizing that sparks realizing the powder of gunpowder Chinese first invented Cannons. Many cultures contributed to the evolution of the gunpowder and its use in cannons after the advent of gunpowder made the creation of the first rudimentary firearms possible. The earliest known Chinese cannons were cast in bronze and were only about 14 inches in
How-to Make Gunpowder During the Tang Dynasty The invention of gunpowder was made to gain immortality, by Chinese alchemists during the 8th century Tang Dynasty (Ross). The results led them accidently to an invention that explodes, which was called huo yao (Guide). Gunpowder was used to to help treat skin diseases and to kill insects (Guide). The Chinese people discovered to their advantage, that the powder could be used as an explosive weapon later on in the 9th century (Guide). Not only was it used for causes such as these, but fireworks were made, for entertainment (Ross).
Relating this back to molar volume, the higher the temperature, the higher the volume the gas occupies. When a certain amount of gas is heated to a higher temperature, the gas particles will have higher kinetic energy. This induces them to move with high speed which is associated by a higher collision rate with other particles. The volume of the gas increases so as to remain a constant pressure. Pressure Law ( Gay-Lussac’s Law ) declare that when the volume of gas is kept constant, its pressure will be directly proportional to its temperature in kelvin.
1. Spanish Arquebus While the history of the new world and the firearm go together hand in hand the more important of these first firearms was the Spanish Arquebus. These guns usually had a long barrel firing a large caliber projectile (by today’s standards) and was shot from either the shoulder or from the chest, sometimes including a rest to aid the shooter when firing such a heavy weapon. The firing mechanism was mealy a lit cord that would smolder, if the cord was to burn out the shooter had to find a way to
The attack, however, failed due to faulty charges and design. Nonetheless, it was the first attempt by a belligerent to use chemical weapons during the war. Germany possessed a significant advantage when it came to the development of chemical weapons. This is primarily due to the massive chemical industry in the country that included corporations such as “BASF, Bayer, Hoescht, and Agfa.” After the failed attack, Germany tried once again by launching 18,000 150 mm howitzer shells containing xylyl bromide at Russian lines. The shells were rendered useless, however, due to the subfreezing temperatures during the winter of 1915.
This essay is about how gunpowder can be used as a good thing or a bad thing and how it is used today. In the first source it stated that gunpowder was an accident by The Chinese and they were trying to make a potion for immortality but instead they ended up with gunpowder. Which contains potassium nitrate, common charcoal, and sulfur. The person who invented the record of gunpowder is Wujing Zongyao, and the first person to create gunpowder was Tang Dynasty and Song Dynasty. Now I 'm going to talk about the positive things about gunpowder, around 1500 the war of medieval ages ended.
Hydraulic fracturing, otherwise known as “fracking,” by definition, means the process of drilling and injecting fluid into the ground thousands of feet deep, at a high pressure; in order to fracture shale rocks to release the natural gases inside (Schrope n.d.). A more adequate explanation on to why we perform the method of “fracking” is that it is an easier process to obtain the natural gases inside the rocks. These natural gases are used for many sources of energy throughout the world. Natural gases have also been proven to be more cleaner and more efficient source than coal. The process of fracking involves drilling through deep wells into the shale rocks which breaks up the rock shales releasing these natural gases.
The percentage of successful collisions may increase or decrease depending on the circumstances of the collisions. Collision theory, proposed by Max Trautz and further added to by William Lewis in 1918, is proven in the results. The greater concentration, or particles in a substance, increases the risk of collisions in a set time. However only a proportion of collisions result in successful chemical bonding. The increased number of particles leads to more collisions and increases the rate of successful collisions and therefore consequently decreasing the rate of
Most of the drugs are polar in nature and preferred phase is the Reverse phase chromatography or High performance liquid chromatography. To make faster instead of a solvent being allowed to drip through a column under gravity, it is forced through under high pressures of up to 400 atmospheres. This is the better separation for the separation of the components in a mixture. Hplc employs a very finely divided mobile phase and a liquid phase. Few thousands of pounds per square inch must be pressurised in order to obtain a satisfactory flow rate.
Furthermore, I have also found a pattern/trend in the graph, the graph has a steep slope only increasing due to the fact that the distance of the elastic band is also increased. The farther the distance of the elastic band, the larger the displacement of the tub will be. The reason behind this is that the longer the distance of the pull-back of the elastic band, the farther the tub will travel is because the farther the pull-back of
