👉 Compressibility is a property of materials that allows them to expand or contract when subjected to a certain amount of pressure. It depends on the material's molecular structure, which can be influenced by factors such as temperature, humidity, and the presence of other substances in the mixture. In general, compressible materials are those that have a high degree of density and low specific gravity (the ratio of mass to volume). This means they are able to expand or contract significantly when subjected to a certain amount of
