The difference between a liquid and a gas is obvious【C1】______the conditions of temperature and pressure commonly found at the surface of the Earth. A liquid can be kept in an open container and fills 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 【C3】______of a planet’s atmosphere. The distinction was a prominent feature of early theories 【C4】______(describe)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 made up of different kinds of molecules(分子). The theories now prevailing【C5】t______a quite different approach by emphasizing what liquids and gases have in common. They are both forms of matter【C6】______have no permanent structure, and they both flow easily. They are fluids.
The【C7】______(fundament)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【C8】______, becomes less dense: some of it evaporates. In contrast, the vapor above the liquid surface becomes dense as the evaporated molecules are added to it. The combination of temperature and pressure【C9】______ which the densities become equal is called the critical point. Above the critical point the liquid and the gas can no longer be【C10】______(distinguish): there is a single, undifferentiated fluid phase of uniform density. [br] 【C5】
