👉 Distensions is a concept in physics that describes the expansion of a substance due to its density. It is also known as volumetric expansion or volumetric contraction. In other words, it refers to the change in volume caused by a change in density. Distensions can occur when two materials have different densities and are separated by a fluid medium. This separation causes the material in one layer of the separation to expand while the material in another layer contracts.
