1. It is an organisms\' occupation. 2. \_\_\_\_\_\_ are the non-living component of an ecosystem. It includes air, water, etc 3. This means a description of the arrangement of atoms, as seen at different levels of detail. If the strain goes away after the load or applied stress is removed, the strain is said to be \_\_\_\_\_. 4. What are the elements that have properties intermediate between metals and nonmetals? 5. What occurs when a substance is transformed into other substances with a totally different composition and properties? 6. A material is said to be \_\_\_\_ if it\'s composition and properties are uniform throughout 7. All forms of matter are composed of the same building blocks called \_\_\_\_\_\_. 8. What is the common unit used to indicate the mass of a particle? 9. The basic repeating unit in a polymer is called \_\_\_\_\_. 10. \_\_\_\_ is formed when a pair of electrons are shared between atoms. 11. How many atoms are there in the unit cell of BCC? 12. 13\. The term \"brass\" is very commonly used to designate an alloy of these two metals, namely: 13. What is widely used as light metal? 14. What element improves the strength and fatigue properties of copper? 15. Silicate mineral having the characteristic properties of fibrous structure and fire resistance 16. A herbivore is also known as \_\_\_\_\_\_\_. 17. A group of living organisms of the same kind of living in the same place and at the same time refers to \_\_\_\_\_. 18. The true end of any food chain is \_\_\_\_\_\_. 19. This refers to the different cycles in the environment such as Nitrogen, Oxygen, Water, Sulfur and Phosphorus. 20. Process during which the temperature remains constant? 21. The-process where no heat transfer in or out of the system occurs known as \_\_\_\_\_. 22. What is the standard temperature and pressure? 23. Heat flow into a system is positive, and heat flow out of the system is 24. The enthalpy and internal energy are the function of temperature for \_\_\_\_\_. 25. When work is dissipated into internal energy, what is the change in the disorderly motion of molecules. 26. What is the Atomic Packing factor of Face centered Cubic? 27. \_\_\_\_\_ is a crucial aspect of materials science and engineering. It involves evaluating the properties and characteristics of materials to ensure they meet specific requirements and standards. 28. Which material property describes a material\'s ability to return to its original shape after deformation? 29. What is the most common semiconductor material used in electronic devices? 30. What property describes a material\'s resistance to fracture when subjected to a sudden impact? 31. What alloy is composed of zinc and copper? 32. What material property describes the materials ability to conduct heat? 33. What property is measured by a material\'s resistance to indentation or scratching. 34. What is the term for the process of converting waste materials into reusable materials? 35. Which air pollutant is known to cause respiratory problems and is commonly emitted by vehicles? 36. This is generated during anaerobic digestion when microorganisms break down (eat) organic materials in the absence of air (or oxygen)? 37. What is the renewable energy source that harnesses energy from the Earth\'s internal heat? 38. Which law describes the relationship between the electric field, electric charge, and distance? 39. Which electromagnetic wave is used for long-distance communication, such as AM and FM radio? 40. Which law describes the relationship between the current, 41. voltage, and resistance in an electrical circuit? Which electromagnetic wave has the shortest wavelength\" 42. Which phenomenon occurs when an electromagnetic wave changes direction as it passes from one medium to another? 43. Which component of an electromagnetic wave is responsible for generating a magnetic field?
