Answer: In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal, and some states only exist under extreme conditions, such as Bose–Einstein condensates, neutron-degenerate matter, and quark–gluon plasma, which only occur, respectively, in situations of extreme cold, extreme density, and extremely high energy. For a complete list of all exotic states of matter, see the list of states of matter.
Or you can put: 1, The temperature often effects a change of the state of matter.
2, Species, then, are real, even if they do not represent different stable states of matter.
3, Hudson's team is focusing on the state of matter that exists at temperatures just above the temperature at which materials start to superconduct.
4, We can easily tell one state of matter from another by their form.
5, The state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility.
6, Changes of state of matter are due to increased motion of molecules.
7, Of relating to, or existing in a state of matter intermediate between liquid and crystal.
