Environmental impact of harvesting and using natural materials
Industrial processes involved in extracting and processing natural materials
Applications of natural materials in different industries and products
Studying these topics will provide a comprehensive understanding of the role of natural materials in our everyday lives and their significance in the fields of science and engineering.
By understanding the properties, uses, and applications of natural materials, we can make informed decisions about their sustainable use and contribute to the responsible management of natural resources.
Energy - A. Energy is involved in all physical and chemical processes. It is conserved, and can be transformed from one form to another and into work. At the atomic and nuclear levels energy is not continuous but exists in discrete amounts. Energy and mass are related through Einstein's equation E=mc 2 . B. The properties of atomic nuclei are responsible for energy-related phenomena such as radioactivity, fission and fusion. C. Changes in entropy and energy that accompany chemical reactions influence reaction paths. Chemical reactions result in the release or absorption of energy. D. The theory of electromagnetism explains that electricity and magnetism are closely related. Electric charges are the source of electric fields. Moving charges generate magnetic fields. E. Waves are the propagation of a disturbance. They transport energy and momentum but do not transport matter.
