Weakly symmetric matter

物质状态 State of matter

(重定向自Weakly symmetric matter)
不同物质状态的相互关系。
用相图表达的物质状态。
分子在液体时的排列情况
分子在气体时的排列情况

物质状态是指一种物质出现不同的相。早期来说,物质状态是以它的体积性质来分辨。在固态时,物质拥有固定的形状和容量;而在液态时,物质维持固定的容量但形状会随容器的形状而改变;气态时,物质不论有没有容量都会膨涨以进行扩散。近期,科学家以分子之间的相互关系作分类。固态是指因分子之间因为相互的吸力因而只会在固定位置震动。而在液体的时候,分子之间距离仍然比较近,分子之间仍有一定的吸引力,因此只能在有限的范围中活动。至于在气态,分子之间的距离较远,因此分子之间的吸引力并不显著,所以分子可以随意活动。电浆态(Plasma),是在高温之下出现的高度离化气体。而由于相互之间的吸力是离子力,因而出现与气体不同的性质,所以电浆态被认为是第四种物质状态。假如有一种物质状态不是由分子组成而是由不同力所组成,我们会考虑成一种新的物质状态。例如:费米凝聚和夸克-胶子浆。

In physics, a state of matter is one of the distinct forms that matter takes on. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many other states are known to exist only in extreme situations, such as Bose–Einstein condensates, neutron-degenerate matter and quark-gluon plasma, which occur in situations of extreme cold, extreme density and extremely high-energy color-charged matter respectively. Some other states are believed to be possible but remain theoretical for now. For a complete list of all exotic states of matter, see the list of states of matter.
