Essays on Halogen

During the inspection of the thermal envelope (insulation) of my residence, major mechanical equipment were evaluated. The auditing also involved conducting various diagnostic tests on residence. The evaluations are geared towards helping me establish and quantify the energy efficiency levels at my residence. The audit indicates that there are many energy consuming appliances at my home and some of them emit energy while on standby mode. The appliances include toasters, televisions, computers, and televisions. These appliances use varied quantities of electricity in terms of Watts (Turner, 2016). Some of the concerns revealed by the audit include air leaks around ...

Feedback refers to information given in response or reaction to a prior behavior in order to influence and bring about an adjustment of the current and future behavior of an individual or group. Feedback is an effective tool for gauging employee performance in the workplace. Effective feedback in the workplace causes the employees to be energized and motivated which in turn leads to productivity in the workplace and employee satisfaction. Feedback helps the employees to develop a sense of identity and to feel part of the organization (Dignen). A manager can give effective feedback to employees, whether positive or ...

Invented and patented by Thomas Edison in 1879, the incandescent bulb comprises of a wired filament placed inside a glass bulb (“The History”). When electricity is provided to the filament, it heats up thereby making the bulb glow and emit light (“Incandescent, LED”). The wired filament of the incandescent bulb was initially made using carbon obtained from a cotton thread that was uncoated. This filament gave the bulb a lifespan of just 14.5 hours. Later, the carbon filament was made using bamboo, which gave the bulb a longer lifespan of up to 1200 hours (“The History”). Much later, in ...

What is the chemical formula for ozone gas?

Ozone is present in the troposphere, a part of the atmosphere. Ozone consist of 3 molecules of Oxygen. The chemical formula for ozone is O3. Ozone is also called as tri-oxygen since it consists of 3 molecules of oxygen bound to each other by covalent bonds. The structure and formula of ozone were identified in the year 1865. However, it is less stable than Oxygen and blue in color.

How does ozone form in the stratosphere?

Ozone is found in both, the stratosphere and the troposphere. The formation of ozone in both these layers is distinct. Stratospheric ozone is formed in two simple steps. Initial step involves ...

Minerals are classified by their chemical composition as Silicates, Phosphorites, carbonates, and halides are all major mineral groups.

Silicates contain silicon (Si) and oxygen (O), the two most abundant elements in the earth and comprise the majority of Earth's crust. They have a chemical formula SiO2. Common silicate minerals include olivine, pyroxene, amphibole, mica and quartz.

Phosphorites are sedimentary rocks of biochemical origin and are rich in phosphate with chemical formula PO4. They are mostly used as chemical fertilizers. They are also used as food preservatives, anti-corrosion agent and also in the field of metallurgy. Limestone and mudstone are common phosphate bearing rocks.Carbonates are the minerals mostly found in the Earth’s near surface crust. They have ...

As a student on campus, I try to be continuously aware of the different measures that the campus and the community as a whole have taken to reduce the overall ecological footprint of the campus. While I understand that implementing a campus-wide change may be a daunting task, there are a number of small, relatively easy changes that can be made to campus policy to reduce the overall ecological footprint of the college community. This will reduce costs to the school in the long run, and also provide students with the skill set necessary to reducing their ecological footprint in their own lives. The ...

Halogen Bulbs - Cellulose Insulation - Aluminum Ladders - Bamboo Fly Rods

Decision making is an important element that associated with an organization for their betterment and long run efficacy. There are basically two broad types of organizations are there known as manufacturing organizations and service oriented organizations, and both of the types of companies are delivering something extra and something new for their end users. In this part of the assignment, it is required to analyze the production system for the Halogen Bulbs, Aluminum Ladders, Cellulose Insulation and Bamboo Fly Roads. Apart from that, it is also required to analyze the most effective cost method that would be effective for ...

Introduction Purpose The purpose of this report is to recommend that best way to save energy used for lighting by evaluating the best time to turn off a light based on the type of lighting used.

Problem

Energy costs are important to lower in order to save on the family budget as well as to decrease the amount of pollution entering the environment. Turning of the lights when a room is not in use has always been a good way of saving energy when incandescent lighting was in general use. A variety of lighting designs are available in contemporary times. Those ...

Introduction

‘Paint the Beat’ is an event aimed at promoting the art and music industry in Melbourne. The event plans at achieving this through collaborating local musicians and artistic painters to create their work of art through a different avenue of inspiration. As music is performed, the painter’s expression of its lyrics increases the audience’s understanding of the same. The guests enjoy the ambience of performance in a completely new light of artistic and musical expression, and also encouraging and supporting local artists and musicians. The event will be held on Thursday, 10 October 2013 at The Leveson, and ...

Incandescent light bulbs emit light by the heating of the filament inside the bulb. First developed by Humphrey Davy in 1802, the earliest incandescent bulbs were made from two charcoal strips with a high power battery used to pass current trough it. The flowing current lead to the production of an intense incandescent light that became the first component of the arc lamp. Future improvement was done by Warren De La Rue in 1820 utilizing the platinum coil inside an evacuated tube. This design was motivated by the high melting point of platinum that would give the lamp a better operation ...
