👉 Non-extensional is a concept in chemistry that refers to a substance that is not capable of being extended, or stretched, beyond its original dimensions. This means that it cannot be compressed or bent into a new shape, as it is originally in a three-dimensional space. Non-extensional substances are often used in materials science and engineering, where they are used for their unique properties such as stiffness, resistance to deformation, and strength. Non-extensional substances can also refer to non-malleable materials that
