Very orderly arrangement
Not orderly arrangement
Force between particles on the surface of a liquid
Liquids resistance to flow
Brake systems in cars, pressure on one end causes on the other end
The amount of force exerted on a given area
For a fixed amt. of gas at constant temp., the volume of a gas increases as it pressure decreases.
For a fixed amt. of gas at constant pressure., the volume of a gas changes
No definite shape and no definite volume. The particles burst open.Examples of plasma is lightning,fire, aurora borealis, and fluorescent lights. Stars are also a good example of plasma
Changes of State
Conversion of a substance from one physical form to another
The measure of how the particles are moving
A reaction that takes energy in( heating)
This gives off energy( losing energy)
Solid to liquid( like ice melting back to ice). Solid substance takes in energy and becomes liquid. This happens at melting pt. Substances have a specific melting point zero degrees
Liquid to gas
Vaporization that occurs throughout the liquid. The temp. This occurs at is called the boiling pt. Water is 100degrees celsius
Vaporization that occurs at the surface of a liquid below its boiling pt.
Solid directly to a gas
Liquid to a solid. Particles lose energy, get closer together and become a solid
Gas to a liquid. Condensation pt. Is the temp. At wich a fas become s a liquid. Ex: water is 100degrees Celsius. Gas particles slow down, begin to clump together and form a liquid Ex: cold glass on a hot day.
