👉 The simply fluid, also known as pure liquid, is a state of matter that consists solely of molecules in constant motion without any fixed arrangement or structure. Unlike solids or gases, where molecules have more defined positions and interactions, in a simply fluid, the molecules are free to move past each other, leading to properties like fluidity and viscosity. This state is characterized by the absence of intermolecular forces that might otherwise impose order, making liquids responsive to external forces and capable of flowing or spreading when disturbed.
