1. Conceptually, the thermal conductivity can be thought of as the container for the medium-dependent properties which relate the rate of heat loss per unit area to the rate of change of temperature. 2. The rate of conductive heat transfer between two locations is affected by the temperature difference between the two locations. 3. Materials with relatively high thermal conductivities are referred to as thermal conductors. Materials with relatively low thermal conductivity values are referred to as thermal insulators. 4. Heat is generally transferred by conduction at considerably higher rates through solids in comparison with liquids and gases. 5. The more vigorous motion of particles is reflected by a temperature increase. 6. Devices that utilize heat to do work are often referred to as heat engines. 7. The state of motion of an object is maintained as long as the object is not acted upon by an unbalanced force.

1. The more the particles vibrate and rotate, the greater the temperature of the object.2. The hotter the object, the more it radiates.3. Heat transfer occurs more readily when the temperature of the surroundings is significantly less than the normal body temperature.4. In winter heat is transferred from the roof of a house to the colder ambient environment not only by convection but also by radiation, while the heat transfer through the roof from the interior to the exterior surface is by conduction. 5. Metallic liquids have much higher conductivities than nonmetallic liquids.

DIALOGUE 1

Mr Clark, a British scientist, is talking to Oleg Smirnov, his Russian counterpart (коллега), at an international conference during a break.

Clark: Your recent experiments have been a great success, Mr. Smirnov. Congratulations!

Smirnov: Thank you very much. You’ve read my last article, then, haven’t you?

C: Of course I have. I’m very interested in your research, and I hardly ever miss your publications. By the way, when are you going to give a talk on your work?

S. Some time next week at the Research Centre, but I can’t tell you definitely yet.

C. Could you ring me up and let me know?

S. Certainly.

C. Thanks a lot.
