Final answer:
The process of creating finer particles by rubbing, grinding, or pulverizing a substance is called trituration. It is an important technique in pharmacy and the chemical sciences for processing substances into finer forms for various uses.
Step-by-step explanation:
The process of rubbing, grinding, or pulverizing a substance to create a finer particle is known as trituration. This term is used particularly in pharmacy and the chemical sciences as a method of fine grinding and mixing a solid substance with an agent to produce finer particles for easier dissolving or processing.
As it relates to the other parts of the original question:
- Filtration is a method used to separate solids from fluids, allowing only the fluid to pass through the filter, resulting in the collection of the solid substance.
- Mechanical digestion, chemical digestion, and ingestion are processes that occur within the alimentary canal, specifically starting in the mouth where mechanical breakdown of food begins.
- Granulation is a term used in metalworking where small particles of metal are attached to a surface, often for decorative purposes.
