Matter solids

Chemistry is concerned with the properties of matter, its distinguishing characteristics. A physical property of a substance is a characteristic that we can observe or measure without changing the identity of the substance. For example, a physical property of a sample of water is its mass another is its temperature. Physical properties include characteristics such as melting point (the temperature at which a solid turns into a liquid), hardness, color, state of matter (solid, liquid, or gas), and density. A chemical property refers to the ability of a substance to change into another substance. For example, a chemical property of the gas hydrogen is that it reacts with (burns in) oxygen to produce water a chemical property of the metal zinc is that it reacts with acids to produce hydrogen gas. The rest of the book is concerned primarily with chemical properties here we shall review some important physical properties. 

The relationship between electromagnetic radiation and matter (solids) is intertwined in the so-called space-time phenomenon. All solids emit photons, even yourself. The concept of absolute zero lies in the fact that no photons are emitted at 0° K. As the temperature rises, a spectrum of photon energies is emitted, as shown in the following diagram, given as 7.8.1. on the next page. 

Electrophoresis can be observed in solutions containing suspended matter (solid parhcles, liquid drops, gas bubbles) in a highly disperse state (Fig. 31.2a). Under the influence of an electric held, these particles start to be displaced in the direchon of one of the electrodes. Often, this movement is toward the negative electrode or cathode hence, electrophoresis has occasionally been called cataphoresis. 

Liquid water is difficult to find in the universe. Scientists have found frozen ice in places such as Mars and gaseous water vapor in atmospheres such as that on Venus. However, no one has been able to find liquid water anywhere other than on Earth. Water is the only natural substance that is found in all three states of matter (solid, liquid, and gas) at the temperatures normally found on Earth. By exploring a few of the properties of water, you will discover what makes water unique. 

Chemical reactions may result from interactions among and between the three phases of matter solid, liquid, and gas. The major interactions that occur in the deep-well environment are those between different liquids (injected waste with reservoir fluids) and those between liquids and solids (injected wastes and reservoir fluids with reservoir rock). Although gases may exist, they are usually dissolved in liquid at normal deep-well pressures. 

The number 4 recurs remarkably often carbon, the central element of life, is tetravalent. Life has four criteria. The genetic code is written with four "letters", which in turn are made up of four elements. (The elements themselves occur in four states of matter solid, liquid, gas, and plasma.) It could, of course, just be a coincidental frequency, as the number 5 is also conspicuously often encountered... 

Note that the diagram has three general areas corresponding to the three states of matter solid, liquid, and gas. The line from A to C represents the change in vapor pressure of the solid with temperature for the sublimation (going directly from a solid to a gas without first becoming a liquid) equilibrium. The A to... 

In flotation, all three states of matter - solid, liquid, gas - are involved and each of these involves surface chemistry. Among the various process steps that are involved are ... 

It is easy to imagine a variety of spectroscopies, as many as the number of possible classifications according to the radiation used and/or the state of the matter (solid, liquid, or gas) interacting with this radiation. The tremendous development of new experimental techniques, as well as the sophistication of those that already exist, is giving rise to the continuous appearance of new spectroscopic techniques. Nevertheless, the different spectroscopies and spectroscopic techniques are rooted in a basic phenomenon the absorption, reflection, emission, or scattering of radiation by matter in a selective range of frequencies and under certain conditions. ...

The previous chapter dealt with chemical bonding and the forces present between the atoms in molecules. Forces between atoms within a molecule are termed intramolecular forces and are responsible for chemical bonding. The interaction of valence electrons between atoms creates intramolecular forces, and this interaction dictates the chemical behavior of substances. Forces also exist between the molecules themselves, and these are collectively referred to as intermolecular forces. Intermolecular forces are mainly responsible for the physical characteristics of substances. One of the most obvious physical characteristics related to intermolecular force is the phase or physical state of matter. Solid, liquid, and gas are the three common states of matter. In addition to these three, two other states of matter exist—plasma and Bose-Einstein condensate. 

These ideas are evident in an essay of Lavoisier s from 1773, in which he identifies the three different physical states of matter solid, liquid, and gas. Here he makes the crucial distinction between the physical and chemical nature of substances, which confused the ancients and led to their minimal elemental schemes. The same bod/, says Lavoisier, can pass successively through each of these states, and in order to make this phenomenon occur it is necessary only to combine it with a greater or lesser quantity of the matter of fire. ...

This microgravily environment gives researchers a unique opportunity to study the fundamental states of matter, solids, liquids, and gases, and the forces that affect them. In microgravity, researchers can isolate and study the influence of gravity on physical processes, as well as phenomena that are normally masked by gravity and thus difficult, if not impossible, to study on Earth. 

PARTICULATE MATTER. Solid or liquid matter that is dispersed in a gas, or insoluble solid matter dispersed in a liquid, that gives a heterogeneous mixture. 

Chemists recognize three main states of matter solid, liquid, and gas. The molecules inside each state of matter move and behave in specific ways, depending on the forces involved. These behaviors determine the two main characteristics that determine an objects state of matter shape and volume.

The Kinetic Molecular Theory of matter attempts to describe all the states of matter and the conversion between the states by considering the structures of molecules comprising matter and how those molecules interact. There are three commonly encountered states of matter solids, liquids, and gases. There are a few other states of matter, such as plasmas, but these are encountered only under extremely high energy conditions. Therefore, we will restrict our conversation to the more mundane states. 

Of the three states of matter (solid, liquid, and gas), only gases have radically changing distances between molecules. When the distances between the molecules of a gas are different than what is found at STP (Standard Temperature and Pressure), we have either a positive or negative pressure (compared to atmospheric).
