) A. Checking your understanding I. Give answers to the following questions: 1) What is the text concerned with? 2) Can you define the general thermal concepts? 3) Do we use the terms «heat» and «temperature» in the same meaning in everyday language and in Physics? 4) What is equilibrium? Give your examples of its understanding. 5) How do you understand the term “thermal equilibrium”? 6) Is there a physical lower temperature limit of matter? 7) What kind of a thermometer is the oldest of all? 8) Do you know how to make a thermometer? 9) When does a material change its dimensions? 10) What does thermal expansion mean at the atomic level? 45 II. Are these sentences true or false? 1. Once all the ice melts, the temperature of the water starts to rise. 2. Temperature isn’t related to the average kinetic energy of the particles (atoms or molecules). 3. Heat is the amount of energy transferred to a system of particles. 4. Nothing can be cooled below - 300 ºC. 5. There is only one way to measure temperature. 6. To make a thermometer, we fill a thin glass tube with water (some use mercury, alcohol). 7. When a material is heated or cooled, it doesn’t change its dimensions. B. Work with language I. Put all possible questions to the following sentences. 1) In everyday language we use the terms «heat» and «temperature». 2) In physics they have different meanings. 3) Temperature is related to the average kinetic energy of the particles. 4) Heat is the amount of energy transferred to a system of particles. 5) We can call this level 0 ºC. 6) To make a thermometer, we fill a thin glass tube with mercury. 7) We put a thermometer in the water.

III. Guess the words: 1) alsce 2) ecloemul 3) mqbiilireuu 46 4) nyexetirt 5) Cuessil IV. Translate the following phrases into Russian and learn them: Up to now, over many years, most recently, shortly after, every now and then, most of the time, throughout the 20 th century, within the next few years, for a while, well before, from this time on, every now and then. C. Activities I. Prepare a presentation on simple physical experiments which you can conduct at home (so there is the stuff you need on your hands). II. Be ready to present and discuss the experiment conducted at home with your partner. |
