👉 Nondiffusion is a term used in physics and engineering to describe the behavior of substances that do not exhibit significant diffusion. This means that the substance does not undergo significant changes as it is heated, cooled, or compressed. In other words, the substance remains in its original state at any temperature without undergoing any physical change. Nondiffusion can be caused by a variety of factors such as thermal expansion, molecular motion, and intermolecular forces. These substances are often used in materials
