Activated Charcoal: (also known as activated carbon): A form of carbon that comes in powder or small granules. It is used to eliminate anything that may be harmful, smelly, or distasteful. Impurities adhere to carbon through sorption (adsorption). As the particle size decreases, the surface area of carbon increases. Similar to sponges, the rough grainy surfaces have numerous pores that offer more space for impurities to stick to.
Adsorb: To stick to or adhere to the outer surface of another material. Sunscreen remains on the surface as it adheres to the skin.
adsorption: The process in which a material sticks or adheres to the outer surface of another material. Sunscreen remains on the skin through adsorption.
carbon: A chemical element that serves as the basic building block of all life on Earth. Carbon can exist in the forms of graphite and diamond. It is a crucial component of coal, limestone, and petroleum, and is essential in forming molecules of chemical, biological, and commercial significance.
fiber: A thread or filament-like shape. (Nutrition) Found in many fibrous plant-based foods. These non-digestible fibers typically come from cellulose, lignin, and pectin, which are plant components resistant to degradation by the body’s digestive enzymes.
Filter: (n.) To block certain materials from passing through, while allowing others based on size or other criteria. (v.) The process of screening various substances based on characteristics like size, density, charge, etc.
liquid: A substance that flows freely but maintains a constant volume, such as water or oil.
Nutrients: Vitamins, minerals, fats, carbohydrates, or proteins that plants, animals, or other organisms require as part of their diet to survive.
particle: A tiny piece of something.
photosynthesis: The process by which green plants and other organisms use sunlight to produce food from carbon dioxide and water.
Physics: The scientific study of the properties and behavior of matter and energy. Classical physics explains the properties of matter and energy based on theories like Newton’s Laws of Motion. Quantum physics is a more refined way of describing the movement and behavior of matter, which emerged as a later field of study. Scientists working in these areas are known as physicists.
pore: A small opening on a surface. In the skin, substances like oil, water, and sweat pass through these openings.
Sound waves: Waves that transmit sound. Sound waves consist of alternating bands of high and low pressure.
Surface area: The amount of surface on a material. Generally, materials with smaller particles and rough or complex surfaces have a higher external surface area per unit mass compared to those with larger particles or smoother surfaces. Surface area is important in chemical, biological, or physical processes that occur on the surface.
wave: A disturbance or variation that moves through space or a medium in a vibrating manner.
