Q1 What are the varioustypes of dry and wet types of corrosion with suitable examples? A1 Anooja Mariya Antony, lives inKottayam, Kerala, IndiaAnswered November 23, 2020 Corrosionis a term used for actual deterioration of metals due to their contact withexternal environmental factors such as oxygen, chlorides, etc. Corrosion is mainly of two types: Dry corrosion / Chemical corrosion Wet corrosion / Electrochemical corrosion Dry Corrosion Itis the formation of oxide or sulfide layers on the metal surface due tointeraction with various environmental factors without any electrolytes. Wecan take the examples of amalgam and silver containing materials. Amalgamgets corroded by action of oxygen on it whereas silver containing materials getcorroded by formation of silver sulfide (black colour) with interaction withsulfides. Wet Corrosion Itis the deterioration of metals with electrolytes present. There will be anelectrolyte acting between the metal and gets them corroded. Wet corrosion has three types under it: ***Galvanic corrosion Stress corrosion Concentrated cell corrosion / crevicecorrosion Galvanic corrosion This type of corrosion can happen in twosituations. One is when two dissimilar metals are used on opposite teeth andother is when a single metallic restoration has heterogenous composition. When two dissimilar metals are in contact,saliva acts as the electrolyte and causes corrosion of metal acting as theanode. In case of amalgam and gold, amalgam actsas the anode and corrodes. Stress corrosion Severely cold worked metals has a lot ofstress and is highly reactive and susceptible to corrosion. When cold workedmetal comes in contact with a metal that is not cold worked, corrosion happensto the cold worked metal. Crevice corrosion This happens when there is difference inoxygen content or composition of the restorations leading to corrosion Prevention of Corrrosion Corrosioncan be controlled by various methods. Passivation. Metals like chromium reactswith certain factors and forms aprotective film over the metal thus protecting it from corrosion. So chromiumcan be added to these restorations to prevent corrosion. Increased content of noble metals. Thisensures decreased reactivity withenvironmental factors leading to decreased corrosion. Polishing. Restorations must be highlypolished and made smooth to avoid anypits or rough surfaces thus increasing corrosion resistance. Otherfactors like making a uniform composition of the restoration, etc are alsoimplemented. My note-*** the technician who came to attend washing machine not properly FUNCTIONING found motor getting heated, due to inflow ofwater was less. He doubted water tap. What a wonder- My tap was giving very small quantity of water.The pipe though GI had corroded inside and gave a block. It was removed andwater flow became alright.It was the problem for not properly functioning ofwashing machine. Q2 If I have not mentionthe branch name to deposit a cheque in SBI, will there be any problem? A2 Kanthaswamy Balasubramaniam Lawyer Mon Account Number - thats all that matters in the CBS world The A/cno is unique and the proceeds of the Cheque will be deposited to the accountnumber. Nobody caresabout the Branch anymore. Q3 When did many peoplestop dressing up to go out of the house such as going to the doctor or simplybeing seen in public? A3 Bhuvana Rameshwar Observe humans July15 Peoplestopped dressing up when others stopped looking. That is the main reason. If I get well dressed but there is noone look at me or appreciate me I might as well go out in the same home clothesor my comfortable clothes as long as it is decent . WhenI was in college I took a whole 45 minutes to get ready because we had lots ofadmirers in friends, college mates and even professors. Each day, what to wear was anart in itself. Theaccessories, the hand bag the colour of the dress or sari was important too.Even now you see the college going and high school students are the onesshowing us the trends and what is latest in fashion. Visit any mall they stand out as the ones askingfor admirers. Afterthat age it is formal dressing for jobs or uniform in some places. So most people are comfortable toget out for groceries or to the supermarket in home or casual clothes. NowI take only 3 min to get ready.. All I need are the keys, handbag and a touchup of lipstick. Home clothes will do. Here in Bangalore acosmopolitan city, no one looks, at others. Allare too busy or not bothered. Now the smart phone is also a good excuse to notlook at others, what withthem forever engrossed in the phone. Someget up from bed and come straight to the shops for groceries or to the self -service restaurant. Nobodycares as long as they are wearing decent clothes. Onlyif it is a wedding invite or a birthday party do people wear good, colourful clothes, silks with ornaments etc.Otherwise it is the same boring blacks and greys in unisex t-shirts, jeans orshorts, some in pyjamas or jogging suits. Q4 Was your mother a stayat home mom? Did it make any difference to how you were raised? A4 Ratnamala Kamath M'com from KarnatakUniversity, Dharwad (Graduated 1988)Sun Yes, my mother was a stay at home mom. Inthe 1960s, 70s and early 80s, there were no TV, no mixer/grinder, no waterheaters/geysers, no washing machines, microwaves. Most cooking and heatingwater for bath was done on firewood. Gas was used sparingly and only inemergencies. Clothes were hand washed, grinding was done on grinding stones. Consequently even though my mother was astay at home mom, she was more busier than the working women of today. Butshe was always there to welcome us home when we returned from school. WheneverI was sick she was by my bedside caring for me. We could share our fears andschool anecdotes with her(when she had the time). Iwas raised with sound values and in a protective environment. I was neverlonely or depressed because couples in those days had more than one kid and ifnot parents I had my siblings, friends and pets for company. The only drawback was I never learnt tobe independent until I got married probably because of the over protective environment at home. Ican't comment on whether it made any difference to how I was raised because Idon't know how the kids of working women are raised today. Q5 What is the differencebetween solid water and liquid water? A5 Shamsundar PerumalAnswered Wed Theyhave, conventionally, different names though the chemical compound is H2O. In solid form it is called ice (you may also call it as solid water);in liquid form it is called water and in vapor form it is called steam or watervapor. Moleculesof solid have least freedom of movement, have least energy and they tend tostick together unless provided with additional energy. Molecules of vapor have high energylevels and move out randomly unlessprovided with physical barrier like pipe, drum, etc. They would move within theconfined space freely till they start losing energy. The liquid is confined to it’s definedspace and takes shape of container itis put in to. Gravity acts on it to bring it down to lowest possible potentialenergy levels, given the physical constraints. Till liquid temperature isuniform, it keeps moving within the boundary space defined by physicalconstraint, gravity and intermolecular forces. Q6 What is a watersoftener loop? A6 Ritwik Sunny, former Customer SupportExecutive at Ashok LeylandAnswered Sun A soft water loop is a copper pipingsystem that reconnects your home's internal water distribution pipes to the water softener. The main use of awater loop is to keep the inside and outside of home's water systems separated. Q7 If you are servingunder two senior officers who always give conflicting orders, what would youdo? A7 Sharda Prasad Former OSD MOS Ministryof Tribal Affairs Govt. Of India (2013–2014)9h ago Normallyit does not happen that way. Between the two seniors one is bound to be moresenior. Secondly both cannot be your immediate boss. You are bound to be officially reporting only toone of them. Solisten to everyone who is senior to you but follow your immediate boss'sdirections. Inofficial work we also abide by rules of business and circulars. My note- Though reporting officer isimmediate superior, many times officers from top level gives instructions. So in my case I would tell myimmediate superior and proceed to carry out the instructions from top level.The immediate superior simply agree and ignore if any instructions given bythem. Q8 Why does rain turn tosnow instead of ice? A8 Karl Brace , Phd Electrical andComputer Engineering, Carnegie Mellon University (1992) Answered 12h ago When rain gets cold it DOES turn intoice. It’s called sleet, or freezing rain, or hail, depending on the conditions. Snow was never rain. Snow started out aswater vapor that condensed at below-freezing temperatures. Soinstead of the water vapor particles condensing onto an existing droplet ofwater, they condense onto an existing ice crystal. And because water moleculeshave a microscopic structure, they preferentially condense onto certainportions of that ice crystal, building the crystal into an intricate form - A snowflake! Eventually the snowflake gets largeenough that the updrafts in the cloud can no longer support it and it falls out of the bottom of the cloud and falls tothe ground as snow. Q9 If soap and water makesthe body clean, what makes a towel dirty? A9 2 AnswersJulie Ann, Stay at Home Mom to2 yr old son at Stay-at-Home Parents (2019-present) Answered 3h ago Imay be completely wrong here…but I would think it would be the dead skin and left over dirt you washedoff in the tub or shower BobIrelan, Still advocating the use of common sense.Answered 3h ago Q: If soap and water makes the body clean, what makes a towel dirty? A: Failure to scrub off the dirt anddead skin when using the soap and water. My note- The soap washes the dirt withthe help of water. But water fullydoesnot fall out during bath. The sticking water is swiped. It contains dirt,dead skin etc. All the above QA are based on Quoradigest to me on 22-7-2021/Answered byme. Quora answers need not be100% correct answers Compiler- R.
