The term "compressible" has been applied in literature to denote the capacity of a material or medium to change its volume under pressure. In one instance, it is simply attributed to soil, implying that the ground can be compacted when force is applied [1]. In another, the term is employed within a scientific examination of gases, where the focus is on the effects of gas expansion in a medium that may be either indefinitely or limitedly compressible [2]. These examples illustrate that "compressible" is used flexibly, spanning both practical descriptions of natural materials and more technical analyses in the study of physical phenomena.
