   Gas 气体


  There are three different kinds of matter. They are solids, liquids and gases. 物质分三种:固体、液体和气体。
  Gas has no shape, so you can't touch gas. 气体本无形,所以你触摸不到。
  Gas moves very freely 1. 气体能非常自由地运动。
  Gas can change into a solid or a liquid when the temperature gets too low. 当温度变得很低时,气体就能变成固体或液体。
  On the other hand, a solid can change into gas when the temperature gets too high. 反之,当温度变得很高时,固体或液体就能变成气体。
  Is there a good example of these changes? 有没有这些变化的好例子?
  Of course, it is dry ice. 当然有,它就是干冰。

adv.自由地,随便地,无拘无束地
  • She was unable to keep back her tears,and wept freely.她抑制不住泪水,痛痛快快地哭了起来。
  • A liquid flows freely and has no fixed shape.液体能自由流动,无固定形态。
