7. Discuss with your partner the physical properties of materials. The following questions will help you. 1. How many groups of concepts can be pointed out when studying the general structure of materials? 2. Can you indicate the components in the first group of concepts? 3. What properties can be attributed to physical properties of materials? 4. What is meant by macroscopic properties? 5. How are the macroscopic parameters of a material determined? 6. What determines the microscopic properties of materials? 7. What discipline explains the behavior of micro particles? 8. Which objects and their behavior are described by the theory of relativity? 9. Under what conditions can the theory of relativity be applicable to small particles? 10. What is the significance of the theory of relativity for nuclear engineers, electrical engineers and production engineers?

Discussion Points on Physical Properties of Materials:

1. When studying the general structure of materials, three groups of concepts can be pointed out.
2. The first group of concepts includes: atomic structure, electronic configuration, bonding forces, and the arrangement of the aggregations of atoms.
3. Physical properties of materials can be attributed to characteristics such as electrical and thermal conductivity, specific heat, and magnetism.
4. Macroscopic properties refer to the material's behavior in bulk, including its flaws, variations in composition, and density.
5. Macroscopic parameters are typically determined through engineering tests that measure properties like mechanical behavior under load.
6. Microscopic properties are determined by the behavior of atoms, molecules, and their interactions.
7. The behavior of micro particles is explained by the discipline of quantum mechanics.
8. The theory of relativity describes the behavior of very large masses (like planets or stars) and objects moving at very high velocities, approaching the speed of light.
9. The theory of relativity can be applicable to small particles when they move at high velocities, comparable to the speed of light.
10. For nuclear and electrical engineers, relativity is significant as it is applicable to phenomena they deal with, such as in particle accelerators. For production engineers, it is primarily of academic interest for completeness.
