Ali Most everyone knows of Solids, Liquids, and Gases, but some do not know of Plasma. The particles in a solid are the slowest. Liquid particles move a little faster. Gas particles move very fast, but plasma particles move the fastest.

made up of atoms; can be referred to as tiny bits of matter. a type of matter that has a definite shape and volume; particles are tightly packed together and that move very slowly. a type of matter that has a definite volume but no definite shape; takes the shape of its container.

a type of matter that does not have a definite shape or volume; the particles move at high speeds and they completely fill the container is a liquids resistance to flow. the particles on the surface of a liquid that has uneven forces acting on them. the total Kinetic & Potential Energy of all the particles in matter.

the average Kinetic energy of the individual particles in matter. the movement of Thermal Energy from a substance at a higher temperature at one at a lower temperature. when a solid state changes into a liquid state. is when a liquid transforms into a solid.

what changes a liquid into a gas. when a gas condenses into a liquid. when a solid turns into a gas; dry ice. when a gas turns into a Plasma.

Vocabulary Deionization: when a Plasma turns into a Gas.

Solids Have definite volume and shape. Is anything that is not liquid, gas, or plasma. Ex: Cell phone, computer, house, and etc. These molecules vibrate in place.

Crystalline Solids Crystalline solids have definite melting points. The molecules are packed in an orderly repeating pattern. The process of forming a crystalline structure from a fluid or from materials dissolved in the fluid is often called crystallization.

Amorphous Solids Amorphous solids are solids with random unorganized molecules. Examples of amorphous solids are glass and plastic. They are considered super-cooled liquids in which the molecules are arranged in a random manner some what as in the liquid state. Amorphous solids also unlike crystalline solids do not have definite melting points.

Liquids These have a definite volume but no definite shape. The volume is definite if the temperature and pressure are constant. Liquids can be anything from water to honey. These molecules move faster than the particles in a solid. It is a fluid (fills its container).

Gases These particles move faster than the ones in a solid or liquid. Does not have a definite shape or volume. Gases also fill their container completly

When a gas is enclosed the pressure increases. That is why when a can of hairspray gets hot it will explode, if it gets shot it will explode, and if fire gets to close it will explode as well.

When temperatures are high enough to remove electrons from their atoms plasma forms. Forms when gas is heated to such a high temperature that the electrons in its atoms gain enough energy to escape from their atoms to make an ion (an atom that does not have an electron).

All mater changes from one to another. Matter is neither destroyed nor created. Only changes shape, size, and other types of matter. Solid to Liquid-Liquid to Solid-Liquid to Gas Gas to Liquid-Solid to Gas- Gas to Solid Gas to Plasma-Plasma to Gas

When a solid melts it forms a liquid. When we melt an ice cube it forms water. The melting point is the same as the freezing point, 0°C. When we melt metal it forms a liquid metal, but unlike water it will harden at room temperature.

When a liquid turns back into a solid it will freeze. Water will freeze at its melting point. When water freezes it will form ice. But liquid metal will harden at room temperature.

When a liquid changes into a gas it is called vaporization. When we boil water it turns into water vapor. If we put our hand over the steam our hand will burn faster than dipping our hands in hot water.

When a gas changes into a liquid it is called condensation. When we take a shower the hot water will make steam, and then we get out and look at the mirror it is foggy and wet.

When a solid changes directly into a gas it is called sublimation. A great example is Dry Ice. It is made up of carbon dioxide and must be froze in the negatives on the Celsius.

When a gas changes into a solid it is called deposition. There is NO natural example of this transformation.

When a gas changes into a plasma it is called ionization. There is no natural way to make a gas into a plasma.

When a plasma turns into a gas it is called deionization. There is no natural way to make a plasma into a gas
