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…...

Energy
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…...

FUEL PRODUCTION WITH THE HELP OF SOLAR ENERGY USING BACTERIAL AND FUNGAL BIOHYBRIDS
Solar energy is present abundant in nature and a renewable source of energy. Plants perform photosynthesis using solar energy which converts CO2 and O2. Likewise, the hybrid system harvests solar energy which enables in fusing with particularly engineered bacteria and fungus, they reacts according to its nature of modification to output the various chemicals and that chemicals can be used in different aspects of manufacturing drugs ,methane and artificial photosynthetic process for carbon fixation. The conversion of CO2 results in…...

Energy Efficiency in Philadelphia
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). Market dynamic explanations are…...

The current social and economic dilemma regarding the storage and usage of electric power must be addressed as the demand for power continues to increase. There are many current forms of energy storage, but new methods need to be researched and developed. As the world moves toward more renewable, clean energy and becomes more aware of the effect on the environment, there will need to be methods in place to accept that change and the continual increase in demand. These…...

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…...
