Gaseous state of matter

Why Do We Need to Know This Material In earlier chapters, we investigated the nature of the solid, liquid, and gaseous states of matter in this chapter, we extend the discussion to transformations between these states. The discussion introduces the concept of equilibrium between different phases of a substance, a concept that will prove to be of the greatest importance for chemical and biochemical transformations. We also take a deeper look at solutions in this chapter. We shall see how the presence of solutes is used by the body to control the flow of nutrients into and out of living cells and how the properties of solutions are used by oil companies to separate the components of petroleum. 

The connection between First Matter and the protyles is obvious. It remains for me to deal with the concept of the Four Elements. These are often thought to denote the hot, cold, moist and dry principles or qualities of bodies but we may also suppose that the elements, earth, water, air, and fire, represent respectively the solid, liquid, gaseous, and what may be called incandescent-gaseous states of matter, although this is by no means a satisfactory or complete interpretation. It must be confessed that the subject of the elements is a difficult one, and I have not yet found explanations for it in the language of modem science. (1913, 43-44)...

Devaux also advanced the important theory that the characteristics of the solid, liquid and gaseous states of matter are retained so long as one continuous layer of molecules remains unbroken. This conception has been partially confirmed by the work shortly to be described. A film may be solid, liquid, expanded or gaseous, and one kind is readily distinguished from another. In certain properties, a solid film of unimolecular thickness resembles quantitatively a three-dimensional solid mass of the same substance, but these properties are necessarily limited to such as can be measured in any given direction. 

This chapter is the first of two devoted to specific states of matter, and in it you will focus your attention on the gaseous state of matter. However, all of the states will be described within a larger framework that looks at the state of matter as a series of interrelated factors, including kinetic energy (or temperature), pressure, and intermolecular forces. Gases are usually described by a series of postulates known as kinetic molecular theory, which constitute the ideal gas law. To begin the chapter, you will look at a historical development of the ideal gas law, during which you will review some of the equations used to create the ideal gas law.

The soil water is the total content of water present in soil pores in the liquid, solid and gaseous states of matter. Liquid water is clearly the usual form of water in soil, and it thus, receives the greatest attention.

Like bulk materials, monolayer films exhibit characteristics that can (sometimes with a bit of imagination) be equated to the solid, liquid, and gaseous states of matter. For films, the equivalent states are roughly defined as...
