Air pollution by Chris Woodford. Last updated: September 14‚ 2014. There’s nothing quite like opening the door and breathing fresh‚ clean‚ air—but how clean is the air you’re breathing right now? Unless you’re a scientist with a chemistry lab at your fingertips‚ there’s no real way of knowing. The gases you’re sucking up through your nose could be slowly killing you: according to the World Health Organization‚ around two million people die prematurely from the effects of polluted air every

Laboratory Ш SEGi University Experiment: Air Conditioning Module Candidate’s Name: Yeap Swee Sean Student ID: SCM-025695 Lecturer: Ms. Chan Yi Shee Date of Submission: 28th November 2013 1. Abstract The main purposes of this experiment are to allow students to get familiarized with air conditioning system and also to obtain experimental data so that the state point can be plotted on a psychrometric chart. The apparatus used in this experiment are SOLTEQ air-conditioning module (Model:HE166-02)

AIR POLLUTION [pic] Introduction The earth’s atmosphere‚ at or near sea level‚ consists approximately of 78 percent nitrogen‚ 21 percent oxygen and 1 percent other gases. If it were possible to remain in this state‚ 100 percent clean air would result. However‚ many varied sources allow other gases and particulates to mix with the clean air‚ causing our atmosphere to become unclean or polluted. Some of these pollutants are visible while others are invisible‚ with each

Research Investigation Safety features in cars Air Bags Air bags are safety features installed in cars so that upon collision the driver limits the damage that is inflicted on him/her. There are several different types of air bags. These include‚ Supplementary Restraint System (SRS)‚ an Air Cushion Restraint System (ACRS) and the Supplemental Inflatable Restraint (SIR). Air bags are commonly known for their rapid inflation upon a collision. They can inflate and deflate within 0.05 seconds

It’s a strange thing when this comes across my mind because usually we don’t look for this in our personality although I’m sure of their existence. Strength and weakness‚ two contradicts that we usually dig for in others‚ but what about us? I really haven’t tried to determine these in me but I’m sure that I have them both. First‚ my points of strength. I know that I’m an intelligent person because I achieved almost everything comes in my way. I’m a confident human. I’m a quick learner so I don’t

Project on Air Pollution BIO-103.3 Summer 2013 Prepared for: Dr. S.M. Mostafa Kamal Khan (SKK) Introduction to Pollution: What is Pollution? Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy‚ such as noise‚ heat or light. Pollutants‚ the components of pollution‚ can be either foreign substances/energies or naturally occurring contaminants. Air Pollution: Air pollution is the

Writing Assignment #1 – Strengths Analysis Throughout my life‚ I have faced with many challenges. From those challenges‚ I have come to learn that life is testing and forcing me to build more positive characteristics to become stronger each day. Hence‚ I can be ready to deal with more obstacles in my future career as an international tax accountant. According to The Clifton Strengths Finder assessment‚ my three strengths are “responsible”‚ which I demonstrated when I worked as a resident assistant

Air pollution Air pollution is a problem everywhere in the world. Local air pollution usually affects big cities. Air pollution becomes a worldwide problem when local pollution moves away from where it came from. For example‚ winds carry air pollution made in the middle of the western part of the United States to Canada‚ like acid precipitation. Acid precipitation Acid precipitation is precipitation‚ like rain‚ sleet‚ or snow‚ that contains acids from air pollution. When fossil fuels are burned
