Q1 Can I take the headphones given to meon Emirates Airlines (economy class)? If they found out I took it would theyfine me or put me in prison? A1 Cynthia MehboobResearcher, Project Associate,Woman, Human.Updated October 27, 2020 I’d start bystating an almost universally held view; headphones onboard aircraft areusually useless. But mostAirlines, including Emirates, are understandably quite touchy about theirheadphones and want passengers to return them. It is not anentirely unreasonable expectation, I’d say. In most Emirates aircraft (not sureabout the A380’s), theflight attendants come to collect the headphones before landing. If you take/stealthe headphones from an A380, I don’t think they would find out in the firstplace. Most aircraft are jam-packed and chaotic especially before and at thetime of landing. However, if they still find out, I think they would take awaytheir headphones at the most and When that happens, don’t complain! You asked for it. would probably fixyou with a loathing stare. A few years ago,travelling from Kuala Lumpur to London, I asked the flight attendant nicely ifI could keep the blanket because I had a long layover in Dubai. She happily agreed. Next time, if youfeel like your heart won’t settle for anything less than aircraft earphones,dare I suggest you resist the urge to nick a pair from under the staffs’ noseand instead request nicelyif you could keep one? Never underestimatethe places a little bit of niceness would take you! But, why try so hard forsome ( let’s be honest, they are useless and quite frankly shoddy) headphones?Word to the wise, if youmust, spend all that energy asking for an upgrade to business class or better:) Q2 Which chemicals are used to purifywater? A2 Kanhaiya Bhatulkar, UPSCAspirantAnswered July 17, 2020 “Millions livedwithout love, none without water!” This dihydrogen infused oxygen molecule forms the basis of all livingforms on Earth. Whether it’s for cooking or basic sanitation needs,the role of water remains irreplaceable as the entire human survival depends onwater. It is estimated that about 3.4 million of the world’s population dieevery year due to deprived access to clean drinking water. Providing safe drinking waterremains a global challenge, for which only chemistry has a solution.Being a boon to the mankind, the chemical industries have come up with variouswater treatment chemicals which will improve access to clean drinking water. WHAT ARE WATER TREATMENT CHEMICALS? Water treatmentchemicals definition can be given in two lines, however, that isn’t ample &would be arbitrary if done. Let’s have a brief introduction on what has made usrely on water treatment chemicals. Contemporarily, thedemand for safe and fresh water is consistently rising, owing to satisfy thehuman needs and to support the industrial activities. With the increasingurbanization and economic development, the current water supply is unlikely tosatisfy the ever growing demands. Hence, the chemical industry uses theinnovative ways of water treatment in order to make water acceptable for end-use,such as drinking, cooking, irrigation and industrial purpose to name a few. The water treatment methods use four basicprocesses that include boiler water treatment, cooling water treatment, waterpurification and treatment of wastewater effluent.The substances that are removed during the water treatment process aresuspended solids, viruses, fungi, bacteria, algae, and minerals. The processinvolves both physical and chemical methods. The chemical used in this processare called water treatment chemicals. COMMON WATER TREATMENT CHEMICALS The most commonlyused chemicals for water treatment process are: Algicide Chlorine Chlorine dioxide Muriatic acid Soda ash orSodium bicarbonate In additions to theabove chemicals, there are numerous other water treatment chemicals used.Coagulants, flocculants, clarifiers and filter cleaners also form an importantpart of water treatment methods. EMBRACING THE FUTURE WATER TREATMENT INDUSTRY The water treatmentindustry is playing an important role in providing clean water globally andprevents various water-related diseases. With the innovative boiler watertreatment chemicals and other related chemicals, water from the sea, pollutedrivers, and wastewater effluents can now be made safe for human consumption. CeraMac at Andijk II,Netherlands have designed and developed a membrane, which unlike thetraditional membranes, offers advanced water filtration. Meanwhile,PWN Technologies a water treatment giant is involved in research to emerge witha unique water treatment solution that’ll help reduce the global water crises.They use the technology that involves suspended ion exchange, ceramic membraneapplications, and advanced oxidation. Q3 Which air conditioner is best in terms ofreduction of electricity consumption? A3 Prasanna Bhalerao Knows about TV,Washing Machines, Refrigerators April 30 An inverter AC is the best to reduce theelectricity consumed. ACs are markedwith Energy Star Rating. 5-star ACs are the best. Note that AC priceincrease dramatically with these options and ratings. Unless one using AC at least 5 hoursper day, it may not be worth paying extra. What matters moreis how the AC is installed. Let me talks about the split AC. This AC has anoutdoor cooling unit and indoor distribution unit. I have often seen theoutdoor unit installed on the full west or south side walls. This is incorrect.What happens is that the harsh sun is beating down on the AC split unit and itis reducing its cooling efficiency. The 1.5T AC may work only as efficient as a1T AC or even less. Installthe AC on the East and North side walls. Elseinstall the AC split unit in an area that has shade most of the day. This alone willincrease the AC efficiency greatly and you will not need to set 20–23° C but a25–27° C will be cool enough. Q4 Why are most foreigners alwaysreluctant to answer the questions asked by Indians? A4 Gopalkrishna Vishwanath I have been amember of Quora since July 2015 Fri (111 words in this answer) I don’t agree thatthis is true. I have beenfortunate to receive many answers to my questions from foreigners. It dependson the question. Most questionsasked by Indians are relevant to India, Indians, Indian politics, Indiancustoms, Indian issues, and events. It is natural thatthese questions will not interest foreigners. And neither will they know enoughabout India and Indian issues/events to be able to answer them. Consider thereverse situation too. Do we Indians answer questions asked by foreigners onissues/events local to them? If we ask questionsthat are truly neutral and choose the right topics they will receive answersfrom all over the world. Q5 Why is temperature less in the boilingwater than water vapour which is produced by boiling water? A5 2 Answers Dennis Pasek, former EngineerAnswered 1h ago It’s probably theway you are taking the measurements. If the water vapor is not saturated, maybe because it hasmixed slightly with surrounding air, or because it has risen a bit andexpanded, the temperature will have lowered slightly. If the water vaporis visible as steam, it is not saturated. If you measure the vapor temperature in an enclosed spacejust above the boiling liquid, the vapor should be saturated and in equilibriumwith the liquid, thus, at the same temperature. Paul Marra, Contractor (1978-present)Answered 3hago I don’t know if itis, but the reason it could be is because water cannot go over its boilingpoint and remain a liquid, but steam can be superheated. Q6 Why does watering plants with urinetend to kill them? 3 Answers Chris Harper Answered Thu Urine contains lots of water and also a bunch ofwastes that your body is trying to getrid of including salt and ammonia. Well uric acid which breaks down intoammonia. Too much of these things are toxic to the plants. It’sone thing to piss behind a tree when you’re out in nature and need to go. It’sanother thing to piss on your flowers in the backyard because you think it’sgood for them. 2ND ANSWER Dan Klein, I use and growmedicinal and culinary herbs Answered Wed It has to be donecorrectly. The urine shouldbe diluted with water first, or the plant will suffer nitrogen toxicity.Try using it diluted with water 10 to 1. Forget about dogurine. Those creatures seem to excrete an herbicide that kills most vegetation.If it could be collected it would make a great organic weed killer. Q3 Why does hospital policy forbid doctorsand nurses from clipping an admitted patient’s fingernails and toenails? A3 Jennifer Larson Studied Nursing atUniversity of South Dakota (Graduated 1996)July 13 It'sbecause of the risk of creating a foot wound on a person with diabetes.The policies generally cover all patients to make it easier to follow. Apodiatrist should be the only person cutting the toenails of a diabetic person. I believe there wasa big lawsuit at one point where a nurse cutting toenails led to a wound, thenan amputation.

A5 Anonymous Answered Tue Green hydrogen is made from regenerative energysources through water electrolysis. With thehelp of electric current, water is divided into oxygen and hydrogen in anelectrolyzer and grey hydrogen derived from fossil fuels is differentiated(such as natural gas) and chemical properties of hydrogen are underappreciated. Hydrogen is safe for atmosphere and can be storedand converted into electricity or heat as required. Green hydrogen is amajor component of energy equation and hydrogen is regarded as a primarypotential renewable energy resource. It is one of the most importantcircular carbon economy (CCE) approaches as it is generated using solar energy. Key factors driving the growth of the greenhydrogen market include a rise in environmental concerns to curb carbonemissions and to switch to cleaner fuelsto attain sustainable development.
