    Discussion/Scientific Explanation: In order to successfully analyze colas, one must become familiar with a Spectrophotometer 20. In order to do this, one must figure out determine the relationship between the wavelength of light absorbed and the color of a compound. Next, one must determine a way to relate the amount of light absorbed with the concentration of the solution. After gaining knowledge about these two parts of the lab, one will be able to determine how a Spectrophotometer 20 can be helpful in determining the concentration of phosphate in colas.3 A spectrophotometer is used to obtain measurements of the amount of light that passes through a object and to measure the amount of light absorbed by a certain material. In order to do this, it is important for one to learn about a spectrophotometer. To use a spec 20, one must plug it in and allow it to heat up for a few minutes. Next, one must enter the desired wavelength and insert a blank cuvette filled with distilled water into the cell compartment.3 For Week 1, five cuvettes were given and were filled with the following: water, red food coloring, green food coloring, a mixture of red and green food coloring, and potassium permanganate. Each material was diluted with water and placed in a separate cuvette so that the spectrophotometer could accurately reveal the absorbance. The cuvette that was filled with water was used as a blank to zero out the spectrophotometer. Each cuvette was then inserted into the…

    The scientific investigation of colloid sand their properties was reported by Faraday (1857) in his experiments with gold. He used the term “divided metals” to describe the material which he produced. Zsigmondy (1905)describes the formation of a red gold sol which is now understood to comprise particles in the 10 nm size range. Throughout the last century the field of colloid science has developed enormously and has been used to produce many materials including metals, oxides, organic sand…

    The water droplets act as prisms because the white light that enters them separate into a spectrum of colours when the light exits and this exhibits the process of dispersion. The spectrum of colours come in the order of red, orange, yellow, green, blue, indigo, and violet, shortly referred to as ROYGBIV, from top to bottom and appear in this order because of their wavelengths, which vary from 400 nm (nanometre or 10-9 m) to 700 nm as shown in the electromagnetic spectrum. In a primary rainbow,…

    By only measuring between one to one hundred nanometres and some weighing less than 10 grams makes the nano drones the smallest drones available. A nano-drone is a billion times smaller than regular drone or 〖10〗^(-9) the size. Each piece of the Nano-drones has to be designed and functioning individually before they can be pieced together to form the final product. The naked eye cannot see the drones when they are one billionth the size of their counterpart. By making the drones to look like…

    colour. Firstly, it is important to say that there are laws governing the world of colour. Colour plays a huge part in our everyday life. If you stop reading right now and just look around, you will see that there is colour everywhere! Is this something that you have taken for granted? Did you know that colour is primarily activated by light? A white light is composed of various colours, which is also called the spectrum. I would not profess to be a scientist but from research it is said that…

    cause solar flares in the first place. Particle acceleration of charged particles is caused when the prominences reconnect as a result of the sudden release of kinetic energy. Particle acceleration causes charged particles are mainly comprised of electrons but also protons and heavier ions to accelerated up to high speeds of close the speed of light with energies up to and beyond 10MeV. When the charged particles interact with the plasma, which has been heated to an excess of tens of millions of…
