The difference between a liquid and a gas is obvious(1)_____ the conditions of temperature and pressure commonly found(2)_____ of the Earth. A liquid can be kept in an open container and (3)_____ it to the level of a free surface. A gas forms no free surface but(4)_____ to diffuse throughout the space available; it must(5)_____ be kept in a closed container, as(6)_____ a planet’s atmosphere. The distinction was a(7)_____ feature of early theories(8)_____ the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be "dissolved" in a vapor without losing its identity, and another theory held that the two phases are(9)_____ different kinds of molecules. The theories now prevailing(10)_____ a quite different approach by emphasizing(11)_____ liquids and gases have in common. They are both forms of matter that have no permanent structure, and they both(12)_____ easily. They are fluids.
The(13)_____ similarity of liquids and gases becomes clearly apparent when the temperature and pressure are raised somewhat.(14)_____ a closed container partially filled with a liquid is heated. The liquid expands, or(15)______, becomes less dense; some of it evaporates.(16)_____, the vapor above the liquid surface becomes denser as the evaporated molecules are(17)_____ it. The combination of temperature and pressure(18)_____ the densities become equal is(19)_____ the critical point. Above the critical point the liquid and the gas can no longer be(20)_____; there is a single, undifferentiated fluid phase of uniform density. [br] (5)
选项
A、however
B、nevertheless
C、so
D、therefore
答案
D
解析
前面一句说到气体会在空气中扩散.此处说要装在密封的容器里,故此空格应填入表“因果关系”的词,此外,分析句子结构,得知空格处应填入副词,D项符合要求。so用于引导从句,不符合语法要求。
