Flammable liquid

Aim - To investigate how the temperature of water affects how salt dissolves. Prediction - If the temperature is warmer, the more solute will dissolve in the solude. Variables - which variables are you going to: Independent Variable - The temperature of the water. Dependent variable - How much salt is needed to not dissolve in water. Controlled variables - The materials. How will you make it a fair test? - Using a machine to weight the salt and heat the water.…

Standard solution is the solution that is been made by dissolving a precise mass of reactant meaning the starting substance in a chemical reaction, and it is important that the mass is weighed accurately into distinguish volume of water that will be used. This tells us that if the concentration of standard solution is accurate then it can also be used to work the concentration of a different solution that it can also react with. Its concentration is generally given in mol dm-3. Standard solution…

Hydraulic fracturing, better known as fracking, is a controversial method of extracting gas and oil by injecting liquids at high pressures into the ground to force open fissures. Although fracking has been around for over half a century, it still remains a very debated topic and for good reason. Fracking has the potential to create jobs, reduce dependence on foreign oil sources, and lower taxes, among many other positive effects. However, fracking is also dangerous to the environment is…

Fracking: A Controversial Topic If someone offered you $100,000 to drill on your land, would you accept the offer? Would the $100,000 be worth the sacrifices? Fracking, or hydraulic fracturing, is the process in which chemicals and liquids are injected into rocks below the Earth’s surface at high pressure to extract the natural gas or oil trapped inside the rock. Below the surface of the United States lies trillions of cubic feet of natural gas, a quantity which is twice the amount of oil in…

When confronted with an obstacle, the easiest and the most efficient way to achieve a resolution is always the most desired; however, when assessing the act of fracking, it may be one hole that should not be drilled. Fracking is the process of using hydraulic machinery to access oil and gas in areas of the Earth’s crust that are otherwise hard to retrieve. Where there are some benefits to using this system, the consequences of fracking are far more catastrophic to our environment. Ethically,…

In this case, if the face part (softer) has some damage, it is possible to change it and maintain the backing part in use. Analysis EXTERNAL ANALYSIS Customer Definition The potential customers for the polyfibron offset press blanket are operations managers, superintendents, and foremen of printers and magazine companies in the US. Potential customers have not purchased the new product before but they know about the characteristics that it needs to have. These characteristics are…

….. Of Life, Taker of Souls People say that the eyes are the windows to the soul, if only they that really meant. If someone is lying, looking a person in they eye will allow to to see right through them. If a person is hurt, sad, or even heart broken, all you have to do is make eye contact to know what they are feeling. The same is for people who are are in love, happy, and glad. The eyes show and see all. But this is only a small part of what I can see when I look someone in the eyes.…

Determination of the gel-point of a resin via DMA testing and its use in a practical sense The DMA is used to determine the modulus values of the resin to associated temperatures and frequencies. The state of viscosity of the resin is also monitored through the evaluation of tan delta values. Gel-point of a resin implies that resin matrix has transformed into an elastic gel state and can no longer flow. The viscosity shows a sudden rise to extremely high values. The time at which this state is…

Where M.R is the moisture loss ratio, M_0 is the initial moisture content, M_t is the moisture content at time t, M_e is the equilibrium moisture content, t is time (minutes), and a, b, c, and k are constants. For the effectiveness of diffusivity, Fick’s equation was used (5) to estimate the dehydration kinetic of different osmotic conditions. M.R=((M_t-M_e)/(M_0-M_e ))=〖8/π^2 e〗^((-(π^2 Dt)/(4L^2 )) ) …(5) Where D is the effective diffusivity, and L is the length of the (cubical) sample.…

In 1854, Dr. John Snow, devised a map of the London Cholera outbreak. He was known to be one of the founding fathers of epidemiology. During that time period, many civilians were dying quickly and rapidly from Cholera (Frerichs). Dr. John Snow suspected the containment was coming from a well known area like a water pump. Snow obtained data of where the individuals lived and the location of the water pumps and mapped the outcome (Frerichs). The map has many different aspects.First, I will…
