What is a Bi-metal stem Thermometer
A bi-metal thermometer is made of a bi-metallic coil. No liquid is used in such Type of Thermometer.
It consists of a bi-metallic strip in the form of along spiral. One end of the spiral is kept fixed, while a light pointer is attached to the other end.
When the temperature rises, the bi-metal strip coil itself into on even tighter spiral due to different expansion rates of the two metals. The pointer moves across the temperature scale and in this way reading is noted.
Note: Another obstacle is the difficulty in learning the language. It is possible that an alien culture will be the main obstacle in learning and in a life that will be difficult to accept. And one more thing – many students are sure about the beauty of free life, not assuming that in foreign universities really have to learn. Lazy and negligent students quickly leave foreign educational institutions. Should I get an education abroad? To clearly answer this question, it is necessary to understand what awaits after leaving abroad, to weigh all the positive and negative points. This should be done by parents together with their future students. It is also important to jointly draw up a plan for further action in the event that a situation occurs. Choosing a country for further education, it is necessary to learn about it as much as possible: about laws, traditions, habits, culture. It is important to know the cost of obtaining higher education abroad. This will be required for the preparation of the financial plan. Before leaving, you need to undergo a medical examination and make the necessary vaccinations.
