Задайте 5 вопросов к тексту: общий, специальный, альтернативный, разделительный, вопрос к подлежащему. Tips For Behaving In A New Office You should be very attentive at work for the first day. It can be really dangerous if your take the first days in your office without much importance. It is a fact that a new employee will be observed at every second. Experienced people in the office will be interested in observing a new employee’s behavior and working style. There may be people who never like a new one in their cabin. You shouldn’t be a victim to their gossips by acting so silly. When you are hired for doing a specific work, you have to take it as worship. Before you join an organization, you should ask yourself whether you want to do this job or not. If the job you got is your dream job, you should dedicate yourself completely in that to excel in the work. If you work hard, you can easily get a good name in your office. Punctuality is a very good habit which is a must for an employee. Everybody likes punctual people. They will call you as ‘the man at the right time’. When the whole world is getting globalized and people do work for numerous clients, time is of course, money. When time is money, each and every minute you spend without a purpose is like wasting money. So reach your office in time or if possible before time. If you reach your office, say thirty minutes before time that will help you organizing the day’s work without any disturbance. You must know your responsibilities. Don’t give a chance to the bullies to turn their machine guns on by being irresponsible. Try to achieve your work target every time, without fail. Check your finished work again and again for making it error-free. You should go through your office manuals and get a clear idea of what is expected from you. When you are confused about any complexities in work, don’t waste your time by exclaiming and using some goofy logic. Seek help of the experienced people in your team. Your concern for the work will be expressed if you ask doubts. If you try to solve the problem on your own, it may take a lot of time and can be a reason for less productivity from your side. Respect your company and take a pride in being the employee of the company. You should get to know the system of the company. If your company is running on a traditional system, do not pose as a revolutionary to change it all. Try to learn the advantages and disadvantages of that system and give suggestions for improvements at appropriate forums.

Воду массой 500 г при температуре 95 °С налили в теплоизолированный сосуд, где находился твёрдый нафталин при температуре 80 °С. После установления теплового равновесия температура воды оказалась равна 80 °С, при этом весь нафталин перешёл в жидкое состояние. Пренебрегая потерями тепла, оцените, сколько граммов нафталина находилось в сосуде. Удельная теплоёмкость воды равна 4200 Дж/(кг · °С), удельная теплота плавления нафталина 150 кДж/кг, температура плавления нафталина 80 °С.
