The other two states other than states of matter (gas, liquid and solid) are Plasma and Hb.
Matter in the plasma state has variable volume and shape and contains neutral atoms as well as a significant number of ions and electrons, both of which can move around freely.
Plasma does not have definite shape or volume. Unlike gases, plasmas are electrically conductive, produce magnetic fields and electric currents, and respond strongly to electromagnetic forces. A gas is usually converted to a plasma in one of two ways, either from a huge voltage difference between two points, or by exposing it to extremely high temperatures.
