Fine particles have a diameter that falls within which range?

Fine particles have a diameter that falls within which range?

• A. 1 nm to 100 nm
• B. 2,500 nm to 10,000 nm
• C. 100 nm to 2,500 nm
• D. 0.1 nm to 1 nm

Answer: (C)

Fine particles are defined by their size, which typically falls within a specific range recognized in scientific literature. The correct answer indicates that fine particles have a diameter ranging from 100 nm to 2,500 nm. This classification is significant in various fields, particularly in materials science, pharmaceuticals, and environmental science, where particle size can affect properties such as reactivity, strength, and the behavior of substances in different mediums. The defined range is important because it allows scientists and engineers to categorize particles based on their size and predict how they will behave in different applications. For example, fine particles are often used in drug formulation because their size can enhance the surface area and improve the bioavailability of active ingredients. The other ranges do not align with the established definitions of fine particles. The ranges outside of 100 nm to 2,500 nm either include nanoparticles, which are smaller, or larger coarse particles that exceed the upper limit of fine particles. Understanding these classifications is critical for anyone studying material properties and their applications.
