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【C2】______it to the level of a free surface. A gas forms no free surface but【C3】______to diffuse throughout the space available; it must【C4】______be kept in a closed container, as【C5】______a planet’s atmosphere. The distinction was a prominent feature of early theories【C6】______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【C7】______different kinds of molecules(分子). The theories now prevailing【C8】______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 flow easily. They are fluids.
The【C9】______similarity of liquids and gases becomes clearly apparent when the temperature and pressure are raised somewhat.【C10】______a closed container partially filled with a liquid is heated. The liquid expands, or【C11】______, becomes less dense; some of it evaporates.【C12】______, the vapor above the liquid surface becomes denser as the evaporated molecules are added to it. The combination of temperature and pressure【C13】______the densities become equal is【C14】______the critical point. Above the critical point the liquid and the gas can no longer be【C15】______; there is a single, undifferentiated fluid phase of uniform density."
【C15】
