  • This question is a little misleading. All of the above are forms of energy or sub-atomic particles. Energy is not matter, so there can be no physical state. Sub-atomic particles and partial-matter also do not have physical states. The reason the various states of matter have their particular physical characteristics and behave in the way they do is a result of the motion of the molecules and the attraction between them. -- States Described: Solid The solid state of matter is when the material has a definite volume or size and distinct shape at a given temperature. Liquid A liquid has a definite volume, but it takes the shape of its container with the help of gravity. Gas The volume of a quantity of gas is dependent on its temperature and the surrounding pressure. If affected by gravity, it will take the shape of its container, but much of it will also spread out into the surrounding area. Plasma At extreme temperatures--such as on the Sun--matter can often lose all its electrons and become ionized. This matter, along with turbulence caused by the heat, results in a phase called a plasma. There is dispute among some scientists whether a plasma is truly a state of matter or just an extension of a gas. -- Fire and radio waves are not matter. They are energy. Fire is caused by the rapid oxidization of certain compounds. Since energy is not matter, it cannot be in a physical state. Though fire can be considered "fluid", it is not actually a liquid. It is energy (or the release of energy). Lightning is electricity (or rather electical discharge). Electricity is the movement of electrons (charge) over a conductor. Electrons do not fall under the laws of physical states. The "states" describe the activity of molecules, not the components of those molecules.. Light is both matter and energy. Some describe it as "partial matter". There is far too much info to take into consideration to delve deeper into that subject. However, since light does not consist of molecules (or even atoms/ions), it belongs to no physical state.
  • Fire and Lightning are both forms of plasma and plasma isn't a completely ionized it's a partially ionized gas that has a certain amount of electrons that are free (not bound to an atom or molecule) also plasma doesn't have to be hot both ionosphere (which is a thin layer of plasma) and interstellar plasma are both very cold.
