[大讨论] 宏观“液体、固体”概念适用的最小几何尺寸

  

   物质有 5 种状态:固体 solid,液体 liquid,气体 gas ,等离子 plasma 和玻色爱因斯坦凝聚 Bose- Einstein Condensate。

请问:

   (1)“液体”概念还能使用的最小几何尺寸是多大?

   类似地,

   “固态”等其他概念?

  

   (2)两个固体之间的一个液膜,薄到什么程度就不传递大气压了?

   液体传递压强,那这个“液体”有适合这个定律的极限尺寸吗?

   Scientists now say that there are actually five states of matter: Solid, Liquid, Gas, Plasma and Bose- Einstein Condensate.

   The Nobel Prize in Physics 2001 was awarded jointly to Eric A. Cornell, Wolfgang Ketterle and Carl E. Wieman "for the achievement of Bose-Einstein condensation in dilute gases of alkali atoms, and for early fundamental studies of the properties of the condensates."
