Explanation & Answer
Thank you for the opportunity to help you with your question!
from Boyle's law, PV=K
this implies that P1*V1 = P2*V2
P1 = 203kPa, V1 = 0.5l
P2 = 50.8, V2= ?
applying the law,
203*0.5 = 50.8V2
thus V2 = (203*0.5)/50.8 =1.998L
thus your answer is 2.00L

The Future of Energy: Guiding Decisions with Evidence
The Future of Energy: Guiding Decisions with EvidenceIn order to reduce the negative environmental impacts of an ever growing human population and increasing demands for energy as technological advances continue, individual countries, states, cities and even households have the opportunity to shift their energy sources to those that are renewable. However, not all locations are equally amenable to any particular form of energy. For this Assignment you will assess your own location, existing energy use, the advantages and disadvantages of different energy sources, and ways to reduce energy demand through conservation. View the rubric.Be sure to explore the following resources to begin your research and to support your ideas with supporting facts. While the provided resources focus on the United States, you are welcome to explore the energy situation within your own state of residence, one that you would like to live in or have visited in the past, and also an international location. In order to focus your discussion, be sure to focus on a specific region.Resources:U.S. Department of Energy:http://www.energysavers.govhttp://energy.govU.S. Energy Information Administration:http://205.254.135.7State energy profiles provided by the U.S.E.I.A.:http://www.eia.gov/stateNational Renewable Energy Laboratory:http://www.nrel.govEnergy4Me:http://www.energy4me.org/energy-facts/energy-sourcesYour Assignment should be written in an essay format, with an introduction and conclusion. The paper will require you to include details from research including the course materials and sources you locate on your own. Use APA format to cite your sources of information, both within parenthetical citations and also within a reference page at the end of the project.Your paper should include all of the following parts.Assess your own energy use: What forms of energy do you currently rely on and where do they originate from? Be sure to consider the energy that you use at home, during travel, and at work or in school. Include at leastfive specific examples. Consider whether each energy source is renewable or nonrenewable.Using the provided materials, determine which renewable sources of energy would be the most and least appropriate for use in your chosen location. Be sure to discuss the energy form identified by your instructor as well as two other forms of renewable energy, for a total of three forms of renewable energy. Explain how you arrived at your decisions. For example, you may find that solar energy is not a potential resource due to seasonal changes making sunlight inconsistently available throughout the year.Discuss the advantages and disadvantages of the energy sources you currently rely on as well as the three renewable energy sources you identified above. Include both the economic (costs/benefits) and ecological impacts of each.Describe how technological advancements have facilitated the implementation of renewable energy technology. Be sure to examine how technology has influenced our ability to generate and distribute renewable energy to a broader consumer base over time.In addition to using alternative forms of energy, energy conservation is also a significant way in which ecological impacts can be reduced on the environment. Determine areas where you may already practice energy conservation and also identify at least three ways in which you can reduce your energy use at home, work, or in other areas you engage in on a regular basis.A template for the Unit 4 assignment is provided. You are welcome to modify this template to suit your needs, being sure to meet the Assignment requirements. Review the rubric for this assignment in the syllabus and the scoring guide for this assignment in Doc Sharing.Basic Writing Expectations:At least 750–1000 words not counting the title or reference pagesInclude a title page, double space, font size 10 or 12Include a highly developed viewpoint/thesis, purpose, and exceptional contentDemonstrate superior organization: use logicFree of grammar and spelling errorsNo evidence of plagiarismUse the APA style for all citationsTurnitin AnalysisA special feature is available to help you with reviewing your Unit 4 Assignment for plagiarism. When you submit your Assignment to the Unit 4 Dropbox, your Assignment will automatically be analyzed by the plagiarism detection tool, Turnitin. Soon after you submit your Assignment, you will be able to view the Turnitin Originality Report. Originality Reports provide a summary of matching or highly similar text found in a submitted paper. When an Originality Report is available for viewing, an icon will appear in the report column of the Assignment Inbox. Originality Reports are only available in the InBox. For this reason, you will need to download the report prior to the grading of the Unit 4 Assignment. To do this, click on the print icon at the bottom of the Originality Report. This will prepare a readable, PDF version of the Originality Report that you can save to your computer.

MOS 6301 Advance hygiene
TEXTBOOK:Fuller, T. P. (2015). Essentials of industrial hygiene. Itasca, IL: National Safety Council.You have completed an analysis of the data from the sampling, you need to understand how the results can be used to evaluate risk. The most common method is to compare the results to some existing occupational exposure limit (OEL). The most commonly used OEL is the permissible exposure limit (PEL) established by the Occupational Safety and Health Administration (OSHA). These are the only OELs that are legally enforceable.The reading in the text this week is from Chapter 5. The study guide also contains two articles and a connection to a web site that you must read. In these readings you will see that there are some concerns with some of the older PELs and that there are other organizations that publish OELs that are based on more recent research and tend to be more conservative than the PELs.There are two parts to the assignment this week, but you combine the two parts into one submittal. First, you will take the results from the calculations you made last week in unit IV and compare them to some OEL. For this part you get to choose whether you use an OSHA PEL or another OEL, Please explain why you chose the OEL. Remember to give an opinion as to whether the risk associated with the exposure is acceptable or not.In the second part take some noise exposure data that are provided and compare the results to the OSHA PEL and action level. This will require performing some more math calculations. You will also have to provide an opinion about the acceptability of risk associated with the noise exposures.InstructionsThis assignment has two parts. Both parts will be combined and submitted within the same document. For this assignment, begin by analyzing the items in the table below and then answering the associated questions.HazardOccupational Exposure Limits (OEL)sManganese Fume 5 mg/m3 (OSHA Ceiling ) 0.1 mg/m3 (ACGIH 8-hour TWA (I))Copper Fume 0.1 mg/m3 (OSHA 8-hour TWA) 0.2 mg/m3 (ACGIH 8-hour TWA)Lead Fume 0.05 mg/m3 (OSHA 8-hour TWA)0.05 mg/m3 (ACGIH 8-hour TWA1,2,4 trimethylbenzene OSHA – None Established25 ppm (ACGIH 8-hour TWA TLV)Toluene200 ppm (OSHA 8-hour TWA)300 ppm (OSHA Ceiling)20 ppm (ACGIH 8-hour TWA TLV) Xylene 100 ppm (OSHA 8-hour TWA)100 ppm (ACGIH 8-hour TWA Metal Working Fluids OSHA – None Established0.5 mg/m3 (NIOSH 10-hour TWA REL) Part I: For each of the chemical hazards answer the following: §Compare your calculated exposures in Unit IV to one of the occupational exposure limits (OELs) in the table. §Does the calculated exposure exceed the OEL you chose? §Discuss why you chose the OELs you used. §Provide your opinion as to whether the risk associated with each exposure is an acceptable level of risk.

Your assignment must use at least two references. One must be gathered from the CSU Online Library; the other may be your textbook. All references and in-text citations must be formatted according to APA standards.
