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 fill
it to the level of a free surface. A gas forms no free surface but tends to
diffuse(扩散)throughout the space available; it must therefore be kept in a closed
container or held by a gravitational field, as in the case of a planet’s
atmosphere. The distinction was a prominent feature of early theories describing
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 that held the two phases are made up of different
kinds of molecules. liquids and gases. The theories now prevailing take a quite
