This chapter contain the physical model and numerical procedure of calculating the dynamics of space charge and electric field distribution in cable insulation material under DC voltage. Electric field distribution and formation of space charge The dependency of electric field distribution on time and temperature is obvious in HVDC system. This is due to the resistivity/conductivity dependency on temperature and electric field [1, 44]. It is also clear that the formation of space charge within…

The reaction between Propanone and iodine under acidic condition Aims To find the order of reaction with respect to propanone, iodine and sulfuric acid, thus proposing a rate equation. Find rate constant at various temperature and with the use of the Arrhenius equation, find the activation enthalpy of the reaction. General Method {For step by step guide of the experiment see preparation page} By using known concentration of aqueous iodine solution (0.000 moldm-3, 0.005 mol dm-3, 0.015…

SCORPIUS Scorpius, also known as Scorpio. Its name is Latin for Scorpion. It lies between Libra to the west and Sagittarius to the east. Scorpius is a large constellation in the southern hemisphere near the centre of the Milky Way. In Greek mythology, Scorpion was sent by Artemis, the goddess of hunting and her mother, Leto, to protect all the creatures since Orion said that he would kill all the creatures on the earth. After a battle, Scorpion killed Orion. Later, Zeus sent Scorpion into…

As human, we used to think ourselves as a superior species with the power to control and manipulate nature as we wish, but in fact we are very vulnerable to natural disasters like volcano, typhoon, tsunami and especially earthquake. For the last decade, we had to face with many super earthquake with magnitude from 7.0 to 9.0 Richter which caused devastating damage, some even send a country backward 10 years in development like Haiti earthquake in 2010 according to the UNICEF. With the power of…

Attending court can be an intimidating situation especially if you have never been to one before. The court that I decided to visit for our assignment was the Harris County Criminal Justice Center located at 1201 Franklin St, Houston, TX 77002. I called prior to attending the courthouse to make sure I had something to observe and take notes from. I spoke to a lady that was very nice and she let me know that there was going to be many docket calls in the court room number 174 on the 19th floor…

I am playing outside in the yard with my dog Rover. Suddenly, I hear an explosive crackling noise that startled me, I turned around to see our house on fire. It seems as if I was in hell fire everywhere and a dusty cloud of black smoke occurred. I panic I can hear screaming from inside of the house. My neighbors running towards the house as I was sitting on the ground in distraught of what I just witnessed. Sitting there with my knees bent against my chest and my arms wrapped around my legs. I…

Girls wear pink. Boys wear blue. Girls stay in the house and do housework; boys like to go outdoors and work. Girls are told to wait their entire lives for the boy they will marry and their happily ever after. Stereotypes surround each and every person. Gender is often one of these stereotypes. Can a girl not enjoy the outdoors? Can a boy not enjoy the color pink? Can a girl not like outfits that contain the color blue? The way that individuals are raised can affect the way they act and…

What is meant by the specific heat capacity of a substance? It is the amount of energy required to increase the temperature of one gram of a body by one Kelvin unit, expressed as J/K/g. The specific heat capacity also can be measured in J/K/Kg and J/K/mol. Substance Specific heat Capacity (J/K/g) Water 4.18 acetone 2.17 hexane 2.26 Compare the specific heat capacity of water with a range of other solvents. The table compares the heat capacities of water and two other solvents. Compare the…

Everyday humans use electricity and other energy sources without thinking about where that power came from, or how it was harnessed. The amazing demand for energy drives innovators to continually think about new innovations to capture and harness power. The massive need for endless amounts of energy is there and few methods alone can match the energy required. In response, humans have begun their quest for a source of energy that is clean and renewable. In a recent survey, 62% of people stated…

The world runs on energy. Very few of us would be alive today if it weren 't for the creation of electricity, a creation that has not only changed the world, but is the first technology to bring us beyond. It has quite literally powered everything since the second industrial revolution. With the strong demand by humans to secure energy came the strong desperation to obtain more of it. We quickly needed it for almost every aspect of modern society. Technology spurs from desperation. We quickly…
