👉 The term "formerly fluid" refers to a substance or state that once exhibited characteristics of liquidity, such as being easily deformable and able to flow, but has since transitioned into a more rigid or solid form. This transformation can occur due to changes in temperature, pressure, or chemical composition, leading to a loss of the ability to flow smoothly. For example, water, which is typically considered a fluid, can freeze into ice, becoming rigid and solid. Similarly, certain materials like wax or polymers can also transition from a fluid state to a solid state under specific conditions. This change signifies a fundamental shift in the material's physical properties, marking its departure from its former state of fluidity.
