Many useful materials can be produced from crude oil. Crude oil can be fractionally distilled. Some of the fractions can be used as fuels. Biofuels are produced from plant material. There are advantages and disadvantages to their use as fuels.
Year 12 HSC Chemistry Notes (Conquering Chemistry) Module 1 – production of Materials Ethylene, polymers and ethanol * Fossil fuels – energy rich substances formed in the Earth’s crust under intense heat and pressure millions of years ago. Originally remains of marine organisms, they were converted into petroleum that is trapped near the Earth’s surface. Fossil fuels can be extracted and refined to provide energy, and the building blocks of crude oil can be used to create numerous materials for human use e.g. ethylene. * Petroleum – mixture of hydrocarbons, consists of liquid crude oil and gaseous natural petroleum gas.
4. Howell iron works purchased came with a furnace which was named Howell Iron works then traditionally pig iron would be worked into wrought iron in finery forges and later putting the furnaces more recently into steel. In these processes, pig Iron is melted and a strong current of air is directed over it while it is being stirred or agitated. This cause the dissolved impurities to be thoroughly oxidized. An intermediate known as refined iron, refined metal, and refined iron.
Because of this, people became specialized in certain skills. Trade was mostly local so businesses were small, and family-owned.3 Water and steam power were soon discovered and machines began to take over human labor. Next came electricity, allowing factories to be built anywhere power was available.3 Most factories ended up being built near cities and railroads so that they could trade. Next, came trade via large shipping containers. Today, much manufacturing is done abroad using materials from all over the world.
Science, Technology, and Economic Systems GKE 1 Task 4 Western Governor's University Science, Technology, and Economic Systems. A. The First Industrial Revolution took place between 1780-1850 (Soomo, 2013). It was a time when new sources of energy, such as coal and steam, were used to power machines designed to decrease human labor and increase production. The technological advancements led to the emergence of factories and an exploding population surrounding them.
Take into consideration the following: The average dairy cow can produce as much as 21 times the amount of waste per day that the average human does (Agricultural Waste Management Field Handbook 4).A large sized CAFO housing 4700 cattle can produce as much waste per day as the human population of Berkeley, CA. Though unlike Berkeley and all other major cities, CAFOs are not home to complex sewage systems. In fact, many CAFOs simply drain the manure into large lagoons that are periodically sprayed onto the land surrounding the complex. This bacteria infested sludge is rich in key nutrients, most notably nitrogen and phosphorous, and is meant to fertilize the land. While this practice may seem environmentally sound, its acumen is dubious at
Question: (TCO 14) Briefly discuss the decision methods used when there is complete uncertainty as to which state in a decision environment may occur. (Points : 10) 2. Question: (TCOs 10,11 and 12) Chad's Pottery Barn has enough clay to make 24 small vases or 6 large vases. He has only enough of a special glazing compound to glaze 16 of the small vases or 8 of the large vases. Let X1 = the number of small vases and X2 = the number of large vases.
National business is a business which is located in the whole country. These types of business normally franchise this is means the governments allows the owner to sells their product or service. International business is a business which is located in more the one country. An example of this would be Tesco or McDonald’s because they’re both located in different countries such as America and England. Size and Scope of Business Small size and scope businesses are normally privately owned or sole traders this is because they have a small amount of employees which means they can’t afford to have more in a small shop.

The factory system replaced the domestic system, in which individual workers used hand tools or simple machinery. It became the characteristics method of production in industrial economies. This system helped to improve the working condition in the industry, on the other side, this system reduced worker’s wage which they depended on for their livelihood.
