The difference between a liquid and a gas is obvious under the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and 【C1】______ it to the level of a free surface. A gas forms no free surface but tends to diffuse throughout the space available; it must【C2】______ be kept in a closed container, as in the case of a planet’s atmosphere. The distinction was a prominent feature of early theories【C3】______ the phases of matter. In the nineteenth century, for example, one theory maintained that a liquid could be "dissolved" in a【C4】______ without losing its identity, and another theory held that the two phases are【C5】______ different kinds of molecules. The theories now prevailing take a quite different approach by emphasizing what liquids and gases have in common. They are both forms of matter that have no permanent structure, and they both【C6】______ easily. They are fluids.
The【C7】______similarity of liquids and gases becomes clearly apparent when the temperature and pressure are raised somewhat. Suppose a closed container partially filled with a liquid is heated.
The liquid expands, or in other words, becomes less【C8】______; some of it evaporates. In contrast, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. The combination of temperature and pressure at which the densities become【C9】______ is called the critical point. Above the critical point the liquid and the gas can no longer be【C10】______ ; there is a single, undifferentiated fluid phase of uniform density.
【C3】
选项
答案
E
解析
空格位于名词theories后,且空格后接了名词短语the phases of matter,因此推测空格处填入现在分词或介词作后置定语。由下一句的两个例子可知,这些理论是“描述”物质阶段的,故选E。下一句并未提到这些理论“驳斥”物质阶段,因此可排除refuting“反驳”。
