This means that a plasma has very different properties from those of an ordinary gas. Plasmas occur naturally in flames, lightning and auroras. Other, more exotic states of matter can occur at extremely high energy levels or at extremely low temperatures, where atoms and molecules or their components arrange in unusual ways. Scientists also sometimes distinguish between crystalline solids where the atoms and molecules are lined up in a regular pattern and glassy solids where the atoms and molecules are attached in a random fashion.
Elements and compounds can move from one phase to another phase if energy is added or taken away. The state of matter can change when the temperature changes. Generally, as the temperature rises, matter moves to a more active state. For example, water vapour gas can condense and become a drop of water. If you put that drop in the freezer, it would become a solid. No matter what phase it is in, it is always water — two atoms of hydrogen attached to one atom of oxygen H 2 0.
In a liquid, the atoms and molecules are loosely bonded. They move around but stay close together. The atoms and molecules move freely and spread apart from one another. States of matter can be more than just your average solids, liquids and gases!
Objectives Differentiate between the three main states of matter. Describe different properties of matter. Describe the properties of a solid, a liquid, and a gas. Describe the properties of a solid and a liquid. Describe the properties of gases and liquids. Understand the transitions between states of matter. Understand how matter changes from one state to another and what affects the change. Describe the processes of evaporation and condensation. Solids can only change shape under force, as when broken or cut.
In crystalline solids, particles are packed in a regularly ordered, repeating pattern. There are many different crystal structures, and the same substance can have more than one structure. Ice has fifteen known crystal structures, each of which exists at a different temperature and pressure. A solid can transform into a liquid through melting, and a liquid can transform into a solid through freezing.
A solid can also change directly into a gas through a process called sublimation. A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite does not change if the temperature and pressure are constant. When a solid is heated above its melting point, it becomes liquid because the pressure is higher than the triple point of the substance.
Intermolecular or interatomic or interionic forces are still important, but the molecules have enough energy to move around, which makes the structure mobile. This means that a liquid is not definite in shape but rather conforms to the shape of its container. Its volume is usually greater than that of its corresponding solid water is a well-known exception to this rule. The highest temperature at which a particular liquid can exist is called its critical temperature.
This process of a liquid changing to a gas is called evaporation. Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container. Gas molecules have enough kinetic energy that the effect of intermolecular forces is small or zero, for an ideal gas , and they are spaced very far apart from each other; the typical distance between neighboring molecules is much greater than the size of the molecules themselves.
A gas at a temperature below its critical temperature can also be called a vapor. A vapor can be liquefied through compression without cooling. It can also exist in equilibrium with a liquid or solid , in which case the gas pressure equals the vapor pressure of the liquid or solid. A supercritical fluid SCF is a gas whose temperature and pressure are greater than the critical temperature and critical pressure. In this state, the distinction between liquid and gas disappears.
A supercritical fluid has the physical properties of a gas, but its high density lends it the properties of a solvent in some cases. This can be useful in several applications. For example, supercritical carbon dioxide is used to extract caffeine in the manufacturing of decaffeinated coffee.

Some chemical properties which make these elements similar are that they are strong reducing agents. The combination with oxygen will oxidize the metals. This is why they are stored in oil ex: Sodium Na is stored in mineral oil. They have also high melting point and they are poor conductors. Bonding in most of the minerals is largely ionic. This type of bond occurs only between metals like gold.
The metals lose their other electrons easily. Therefore because the hydrogen and oxygen atoms are different in size and electronegativity the water molecule is non-linear and dipolar. When two water molecules get close to one another, the oppositely attracted parts of the molecules attract each other. This type of attraction is called hydrogen bonding.
This polarity means that individual water molecules can from hydrogen bonds with up to four other water molecules. Although these individual hydrogen bonds are weak, together they make water a much more stable substance. Unsaturated solution - a solution containing less than the maximum amount of solute that will dissolve under a given set of conditions.
Supersaturated solution — The particles in suspensions are larger than those found in solutions. Components of a suspension can be evenly distributed by a mechanical means, like by shaking the contents, but the components will settle out. Example: Oil and Water. So water may move very quickly because it has a high viscosity, but oil has a high viscosity so it moves slower.
If something were to have a very high viscosity then it may seem like a solid but it would be an amorphous solid. An amorphous solid is a liquid that looks like a solid but doesn't have crystals so it just sits there for a long time and slowly moves. A solid has viscoplasticity, which is the resistance to flow under plastic deformation. If you were to punch plastic with your hand it would deform then go back to shape, but if you were to hit it with a steel pipe there would be a dent in the plastic and it wouldn't go back to its original form.
If all of the energy levels in the atom are full populated with electrons, it is said to be stable, and in most cases, is therefore unreactive. Examples of this include the noble or inert gases such as neon or argon. However if the outer energy level of the atom is not stable, it will automatically try to either gain or lose electrons to become stable. This is achieved by an ionic reaction.
Ionic bonding occurs when the outer atoms of on material changes orbit and joins another material for example: Sodium chloride As you can see, sodium is a group one metal it has one electron on its outer energy level so is therefore unstable. When cut, it possesses a silvery-white color that quickly changes to gray due to oxidation. Lithium has a very low density of 0. It is the least dense of all elements that are solids at room temperature, the next lightest solid element potassium, at 0.
This means that the molecule is relatively dense. There is more weight than there is volume. Aspirin is described as odorless and colorless to where the color is white. It looks like a crystal-line powder at room temperature. It is a relatively stable molecule that should be stored at room temperature 2.
At room temperature and low illumination, pure or so-called "intrinsic" semiconductors have a high resistivity. But the resistivity can be greatly reduced by "doping", i. There are 2 kinds of.

Solids, liquids, and gases are the three main, or fundamental phases of matter. Each one has a different density and a different level of stability.
What determines the stability of each phase is the bond between it's atoms. The tighter the bond between it's atoms the more stable that phase of matter is. Solids are the most stable form of matter, followed by liquids, and then gases. Solids have a definite shape and do not take the shape of their container. Liquids do not have any definite shape and do take the shape of their container, the same is true with gases.
Once again it is the bond between the atoms of liquids, and gases that make it have no definite shape. The first phase of matter is solids.
This zone of weak material exists below a depth of about km and in some regions extends as deep as km. The rock within this zone is easily deformed. The solid rocky shell that extends from the base of the…. Yes I have used Arial 11pt font, 1. Specific Content Criteria Fail Marks 0 — Unit 3 Lecture Study Guide 1.

Regarding the following characteristics how are liquids different from gases?
Expansion Liquids have limited expansion. Gases will expand to fill the container they are in. Shape Liquids and gases have no definite shape. Volume Liquids maintain volume while gases expand to fill the volume of their container. Compressibility Gases have high compressibility while liquids have low compressibility e.
Density Gases have low densities while liquids have high densities relative to gases. Describe how the presence of a constant vapor pressure is an example of a dynamic equilibrium. Constant vapor pressure means that the system has reached dynamic equilibrium since the rate of the liquid particles becoming a gas is equal to the rate of the particles of gas becoming a liquid. Why is evaporation an endothermic process?
In order to change from a liquid to a gas requires the absorption of energy. At higher altitude there is less atmospheric pressure and so the water boils at a lower temperature. At altitudes below sea level there is more atmospheric pressure and water boils at a higher temperature.
