👉 In physics, fluids are substances that can flow and take the shape of their container. There are three primary types of fluids: liquids, gases, and plasmas. Liquids have a definite volume but take the shape of their container, maintaining a constant density and surface tension. Gases, on the other hand, have no definite volume or shape and expand to fill any container they occupy, with particles moving rapidly and randomly. Plasmas, often called the fourth state of matter, are ionized gases with charged particles and can conduct electricity, appearing as a fluid but exhibiting unique properties like magnetic interactions. Each type of fluid behaves differently under various conditions, influenced by factors such as temperature and pressure.
