Studied by 3 peopleFinite Resources
Resources from the Earth, oceans, and atmosphere that have a limited supply and will eventually run out.
Potable Water
Water that is safe to drink and must have sufficiently low levels of dissolved salts and microbes to be considered safe.
Desalination
Process of removing salt from seawater to make it suitable for drinking, which can be done through distillation or processes with membranes like reverse osmosis.
Life Cycle Assessment (LCA)
Evaluation of the environmental impact of a product throughout its entire life cycle, including extraction of raw materials, manufacturing, use, and disposal.
Corrosion
Destruction of materials by chemical reactions with substances in the environment, such as rusting in the case of iron, which can be prevented by applying coatings like greasing or electroplating.
Alloys
Mixtures of metals with small amounts of similar metals to enhance their properties, such as making them harder for everyday use, like bronze (copper and tin) or stainless steel (chromium and nickel).
Thermosoftening Polymers
Polymers made of individual, tangled chains that melt when heated due to weak intermolecular forces, requiring less heat energy to break the chains.
Thermosetting Polymers
Polymers with cross-links between chains that do not melt when heated, providing more strength and stability compared to thermosoftening polymers.
The Haber Process
Industrial process to produce ammonia from nitrogen and hydrogen, used in the manufacturing of nitrogen-based fertilizers to enhance agricultural productivity.
NPK Fertilizers
Fertilizers containing compounds of nitrogen, phosphorus, and potassium, essential for plant growth and can be produced through various integrated processes using raw materials like ammonia and phosphate rock.
