The propylene glycol is considered to be one of the common organic compounds which can be used in many life applications. It can be used in antifreeze, pharmaceuticals and many applications as well. It can be produced by hydrolysis of propylene oxide that is accelerated by the catalysis of base or acid. The goal of the experiment is to produce propylene glycol using water and propylene glycol as a reactant to synthesis propylene glycol. The purpose of doing this experiment is to converge and…

The objective of this lab was to figure out how to determine the range from a given set of velocity and height from the ball. The height of the ball when it leaves the horizontal projectile is at 93.5cm or .935m. The velocity of the ball was .0674 seconds in the range of .1 meter. Creating a total velocity of 1.484m/s. To calculate the hang-time the formula: y= -4.9t^2 was used. The hang time is used to figure out how long the ball will be in the air for. After you find the answer, the time is…

Physics Behind Archery Physics A Exam Paper Morgan Avink 11/18/13 The bow and arrow have been around for many years. The bow and arrow were used for wars in the beginning however they were more efficient for hunting and that is what they are continually used for even today with the dangerous substance of gunpowder that could be used. Guns are cool however the physics behind them is nowhere near to the elaborate physics involved in archery. Today we have three common bow types; the longbow,…

Pure metals are of very less application in engineering as of the need of conflicting property requirement. For e.g. an application may need a material that is both hard and ductile, there is no any such kind of substance existing in nature. For this present problem, combination (in liquid state) of one material with other material is used. This mixing of materials in the molten liquid state is termed alloying ,that provides a property that is not similar to the original materials. Bronze…

Human beings (endothermic homeotherms) maintain their core body temperature around 37°C (98.6° F) by homeostasis in response to changes in the surrounding temperatures and do so through conduction, convection, radiation and evaporation. The hypothalamus of the brain, kidneys and liver are the organs that help control homeostasis and it is thermoregulation that plays a vital role in homeostasis for the stability of our body temperature. Homeostasis, keeping the balance: An important role in…

concept of energy is very important to know because it is used in everyday life. Energy is used when getting out of bed just to dread going to school, heating up left overs, and even boiling some water. Energy cannot be destroyed or created, only passed from one object to another. A great example of energy is the transfer of heat. An ice cube sitting in the hand of a person can show energy at work. Heat from the hand causes the cube to melt and change forms into liquids. To understand energy a…

Throughout the body the skin thickness varies in sizes, the eyelids and lips are the thinnest and the thickest is the soles of your feet. The production of heat is when it is generated by the metabolic process which takes place in the body. Even though energy is released during chemical…

that you are not experiencing gross heat loss trough your attic is to check your roof just after a fresh snow. Additionally, you can request an energy audit from a professional. Many cities, counties and utility companies offer free energy audits to residents and customers. If heat loss is found, measures can be taken to ensure that your home is more energy…

The light bulb uses conductivity, acidity, and electricity. Acidity is a source of electricity and comes from some fruits and vegetables. It is a substance that over time with help from sun and air dissolves metal. The chemical energy, in the acid, is converted into energy that lights up the light bulb. There are weak acids and there are strong acids, they are categorized by their ability to conduct electricity. The acid contains…

When you buy an older home, it is likely there are home renovations happening in your future. Plumbing renovations will not only improve the water efficiency and water quality in your home but will also help to increase the value of your home for when you sell it at a later time. While you will need a licensed plumber for much of this project, there are ways you can help to save costs. Here are two helpful tips to help you have perfect plumbing, but without the full-cost price tag. What Can You…
