The Significance of Chemical Changes in Science
A chemical change is any change that results in the formation of new chemical substances, In the following experiment, a solution that begins with copper nitrate II will undergo a series of chemical changes. Examples of evidence for a chemical change include temperature change, color change, precipitate formation, and gas given offl During a change of temperature, a solution is exothermic meaning there is an increase in the speed of molecules. Exothermic is the taking in of energy When a…...

Scholarly Writing and Plagiarism
Grammarly and SafeAssign are tools that are newly introduced to me. These tools have proven to be great resources to utilize as a Walden student to check my work and to ensure references citing errors. It was necessary to read Patricia O’Conner’s writing posted on the blackboard (Walden University, n.d.) three times on three different days before I could begin the assignment. After working hard to paraphrase the writing, I ended up with a summary of 498 words. I stepped…...

Causes of Health Problems in Miners
Many coal miners breathe in the pollutants of coal dust and one of the effects of coal mining is the development of black lung disease. It is caused by long-term subjection to coal dust. Dust particles collect in the tissues of the lungs and it results in injury to the lungs. Besides creating critical health problems for coal miners, there are also serious health problems that can occur outside of the mine and above ground. Those who live relatively close…...

Building Energy Consumption Evaluation Methods
Several methods and tools have been developed over the past two decades aimed to evaluate energy consumption in buildings; in response to the implementation of regulations on energy use in buildings. Evaluation of energy performance for buildings has been carried out using benchmarks. These benchmarks are usually as a result of building audits and surveys to establish what is typically accessible or extant conditions (Vaezi-Nejad, et al., 2003) (Krarti, 2012). The overall understanding is that if the current situation is…...

Heavily informed by the Civil Rights Movement, the Environmental Justice movement for minorities and people of color is constructed by agendas surrounding autonomy, land rights, and human rights through the redefining of how African Americans and minorities relate to the environment (Taylor 2000). Proponents of classical economic theory argue poverty is the main factor for distribution of environmental hazards, and African Americans and minorities are most affected because they are disproportionately poor (Mohai and Bryant 1992).

Analysing the energy use in buildings can be as complex as the construction of the building itself. In order to lessen the impact on energy on the environment, building energy performance assessment is often undertaken to determine its performance in relation to other buildings and the built environment in general (Douglas, 1996). The performance result is been used to define what is regarded as typical. Hence, forms the benchmark upon which improved performance is pursued. The methods of assessment have…...

Energy use and efficiency in modern communication systems: a review
We can clearly differentiate two different trends: there are constant power value of about 3.5 kW for the morning and the night time, it is an oscillating trend, with an average value of about 5 kW for the fieriest hours and the late evening. This is a not a shocking trend if we consider that in the first case the consumption is due only to the transmission functions, but in the second case besides the transmission functions there is the…...

Force and Motion Predicting Motion
Newton’s Law of Motion helps people predict how an object with rise or fall. To predict motion, you can use a ball or a piece of paper. If you drop a ball from 1,000 ft. will it bounce higher than how far it fell, or will it only bounce half way (500ft)? Newton’s first Law of Motion states that an object at rest will stay at rest, thus, for example, if the human body was to stay still instead of…...
