21. Physicists have observed quantized states of matter under the influence of gravity for the first time. 22. Plasma is often called the " fourth state of matter " after solid, liquids and gases. 23. Distinct phases may be described as different states of matter such as,,, or Bose Einstein condensate. 24. In classical physics, there are only three possible states of matter : solid, liquid and gas. 25. Superfluidity is a special quantum state of matter in which a substance flows with zero viscosity. 26. For a comprehensive listing of these exotic states of matter see list of states of matter. 27. Like states of matter ( solid, liquid, gas, plasma ), matter is a state of energy. 28. For a comprehensive listing of these exotic states of matter see list of states of matter . 29. Plasmas are states of matter formed when atoms of superheated hydrogen gas from water are fused. 30. Through their investigations, they discovered a new state of matter and helped to revolutionize modern physics.
