The Chemical Composition of Air

Nearly all of the Earths atmosphere is made up of only five gases: nitrogen, oxygen, water vapor, argon, and carbon dioxide. Several other compounds are also present. Although this CRC table does not list water vapor, air can contain as much as 5% water vapor, more commonly ranging from 1-3%. The 1-5% range places water vapor as the third most common gas (which alters the other percentages accordingly). Below is the composition of air in percent by volume, at sea level at 15 C and 101325 Pa.

3 Vital Tips for Your Internship Abroad

So, you’re planning to go for an internship abroad. Get you! You’ve got your paperwork sorted, your bags packed, and all your leftovers stored in your parent’s basement. Surely the only thing left to do now is drive to the airport, hop on the plane, and then rock up at your new internship with a phrasebook in hand and a positive attitude, right? Sure, but it’s worth bearing in mind these tips when it comes to interning abroad. Tip #1. Pick the Right Country This seems like the easiest option on the list. Sun! Sea! Sand! Culture! All of the above! And while it might be pretty damn tempting to go straight for the beautiful rolling beaches and party spots, remember that you’ll be interning here, not holidaying. Sure, you’ll be able to head out on the town now and again, but do you really want to find yourself stuck in a party town where you can’t party? Take into consideration the culture, too- is there any part of their society that you need to know about, such as social norms or modesty expectations? Be sure that their outlook on life will at least jibe with yours while you’re there. And last but not least, look at the political situation, as you don’t want to find yourself stranded in a foreign country with nowhere to stay while a civil war rages on around you (note: worst case scenario). Tip #2. Look into the Company Sure, you’ve probably heard a lot about the company you’re going to be interning for where they stand in the market, what kind of work they currently do, why interning for them is the best choice you could possibly make. But there are other important factors to take into consideration, too. See if you can find someone who’s already interned with them, even if it’s just to send them an email or two. Ask them the questions the company can’t answer themselves: were they friendly? If you’re living in a foreign country away from your friends and loved ones you’re going to want workmates who’ll at least put up with showing you the nice drinking holes. Did they keep in contact after the internship, or at least offer references if you did a good job? Never underestimate the power of contacts. Whatever you ask, make sure you know as much as you can about what you’re getting into before you hop on that plane. Tip #3. Work Out What You Want It’s a good idea to sit down and try to work out exactly what you want from this internship. If you’re just going because it’s in another country, rethink your stratagems could you find a more appropriate internship in your own country and then save up to visit later? Make sure your brain has switched from â€Å"party mode† to â€Å"work mode† before you arrive at baggage handling, as you’re going to struggle if not. And most of all, set yourself up for an amazing time, and bring back a thousand stories to make your boring stay-at-home interners sick with jealousy. That’s what it’s all about, right?

Literature Review Language Attitudes - 2398 Words

Literature Review Draft 1. Introduction to language attitudes Language attitudes, which include people’s perception about the language variety in their own community and language varieties in other communities, has been one of the crucial topics in sociolinguistics since 1960s. When people speak of affective qualities of a language variety, it is not the language that is being evaluated, but an underlying stereotype of the speakers themselves. For this reason, attitudes toward divergent language varieties â€Å"are better understood as attitudes towards the members of language communities† rather than the variety itself (Edwards, 1994, p. 89). In this way, then, by judging the speakers of in-group language varieties, respondents are also indirectly evaluating members of these in-groups as well , essentially making qualitative judgments regarding language and their own group identity (Edwards, 1985). Fundamentally, as Edwards (1985) writes, language attitudes â€Å"allow some insights into the perception and presentation of identity† (p. 151). Therefore, by looking at attitudes of learners of Mandarin toward regional accented-Mandarin, we can probably understand whether this language variety is more likely to be used, emulated, and accepted thr oughout learners of Mandarin. The way to figure out what are people’s attitudes towards a language variety is to conduct attitude surveys.

3 Types Of People Essay Example For Students

3 Types Of People Essay In life, there are certain stages one must go through to obtain ones self-identity. These stages are the carefree years of ones youth, the rebellious teenage years, and the passage from a teen into a mature, young adult. Children have the best life. They dont have to wonder and worry. Teenagers have the rebellious, careless type of lifestyle that often gets them into trouble. Young adults look back on their childhood and on their teenage years and laugh at the wonderful memories. In the eyes of children, there is no worry. The days are made to play, and to explore a world that is shinning like a new penny, and as magical as their imagination wants it to be. They make wonderful memories like tasting a fresh orange, and the juice dripping down his/her chin and seeing a butterfly take flight and trying to catch it to feel the soft velvet wings. Children have an uncanny ability to learn. They are full of questions. If given the opportunity to be able to ask these questions and receive the right answers, the constant learning process in children will never cease or be extinguished. There are things one does as a child that are never forgotten. Memories that would bring a smile to the face are sometimes pushed to the back of the mind, but they are never lost. Some of these things are making mud pies, tasting of a favorite food, playing of favorite games, running after fireflies in the dark to make a makeshift flashlight, or a first outing trip to an amusement park. Children have a carefree life, full of surprises and adventures. Kids have the opportunity to be themselves, because at this stage, the pressures of adulthood have not been bestowed upon them. Society has placed a label on the children of todays world. They view the child as sweet and innocent, unlike their older part: the teenager. The teenage years, also called the rebellious years, are one of the most strenuous times of a young persons life. The thought of being told what to do can sometimes overwhelm even the most well adjusted teen. There are new things to explore, some of which may not be appropriate, or for that matter, even suitable for this time of their lives. The teen faces emotional and sometimes physical abuse that in turn lowers the self-esteem of the individual. Some teens face adulthood early by being thrown into a situation like pregnancy. Teens act differently than any other age group. They feel like they own the world and that it should revolve around them and only them. Teens have the most stressful, complicated life of any age bracket. They must put up with the stereotype label of a lazy, rebellious generation that society has placed on them. Adults label teens by the clothes they wear and the people they hang around with. These classifications also influence the placement of teens into different categories among other teens. Due to stressful, agitated,  decisions on how to be perfect and popular, teens need a way to get away from it all. While others may find refuge in sports, music, or religious associations, drugs and alcohol become a key factor in the lives of the other teens. When in teenage years, the individual may not feel like this is the best time of his/her life. Once adulthood is reached, they will realize that the major stresses of the teenage years are just minor problems compared to the situations adults face. The next group of people, the adults, have new situations to face. They must choose a career. This means they need to decide whether to school to get a degree or enter the work force right out of school. Sometimes life makes those choices easier for them by supplying key factors like money and accompaniment, which every adult needs. Adults often face the stressful problems that teens face also. Drugs, alcohol, and pregnancy plague the lives of many adults today. The stress of losing a job or not being able to find one can drive an adult to using drugs or drinking alcohol. The idea of starting a family may scare many adults. They worry about not having the money to care and provide for their children. They often wonder if the child is making the right decisions, and often try to decide for them. Finding time for work and finding the time to be with a spouse are some of the stressful problems adults face today. .u7935ac74a08b71414453c7515a632928 , .u7935ac74a08b71414453c7515a632928 .postImageUrl , .u7935ac74a08b71414453c7515a632928 .centered-text-area { min-height: 80px; position: relative; } .u7935ac74a08b71414453c7515a632928 , .u7935ac74a08b71414453c7515a632928:hover , .u7935ac74a08b71414453c7515a632928:visited , .u7935ac74a08b71414453c7515a632928:active { border:0!important; } .u7935ac74a08b71414453c7515a632928 .clearfix:after { content: ""; display: table; clear: both; } .u7935ac74a08b71414453c7515a632928 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u7935ac74a08b71414453c7515a632928:active , .u7935ac74a08b71414453c7515a632928:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u7935ac74a08b71414453c7515a632928 .centered-text-area { width: 100%; position: relative ; } .u7935ac74a08b71414453c7515a632928 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u7935ac74a08b71414453c7515a632928 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u7935ac74a08b71414453c7515a632928 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u7935ac74a08b71414453c7515a632928:hover .ctaButton { background-color: #34495E!important; } .u7935ac74a08b71414453c7515a632928 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u7935ac74a08b71414453c7515a632928 .u7935ac74a08b71414453c7515a632928-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u7935ac74a08b71414453c7515a632928:after { content: ""; display: block; clear: both; } READ: On the Roads optimism EssayDealing with stressful bosses at work, household chores, automotive repairs, and their financial situations complicate the adult life even further. From the action packed, bright childhood of a youngster, to the slow, gray life of a senior adult, one is preparing oneself for the real world. As children, one cannot wait to grow up into a teenager. As teens, one wonders what happened to the carefree days of his/her youth and anticipates what lies ahead. As adults one often looks back at the best years of their lives. They wish they could go back to those days and relive it all over again, but as mature adults, they know it is not possible. All they can do is talk about the past and try to teach younger generations from their experiences.
