Bulk expansion refers to the increase in volume of a material, typically solids or liquids, when subjected to changes in temperature or pressure. This phenomenon occurs because the particles within the material move more vigorously as temperature rises or experience reduced external pressure, leading to greater spacing between them. Bulk expansion is an essential concept in fields like materials science and engineering, where it impacts the behavior of materials in various applications, including thermal expansion in construction and manufacturing processes.
