What is the property of a material where the content is continuously distributed throughout its mass?

The property of a material where the content is continuously distributed throughout its mass is referred to as homogeneity. In a homogeneous material, every part of the material is identical in composition and structure, meaning that there are no variations in the properties at different points within the material. This uniformity leads to predictable and consistent behavior under various conditions, which is crucial in engineering applications.

On the other hand, plasticity and malleability describe a material's ability to deform under stress. Plasticity is the ability of a material to undergo permanent deformation without breaking when subjected to an external force, while malleability refers specifically to a material's capacity to be shaped or formed, usually by compressive forces. These properties relate to how materials respond to forces rather than their internal composition and distribution throughout the mass. Thus, the distinction is clear when focusing on the characteristic of consistent material distribution, where homogeneity is the key term.
