👉 Rheology is a branch of physics that deals with the behavior and properties of liquids. It focuses on how substances move through each other, such as in a liquid or gas, and how these movements are influenced by factors like temperature, pressure, and charge. The study of rheology includes methods for measuring viscosity, elasticity, and other physical parameters associated with fluid motion, and it is an essential part of many scientific and engineering applications, including materials science, industrial processes, and medical imaging.
