has a definite shape and a definite volume
What are the molecules of a solid doing?
the molecules are closely locked in position and can only vibrate
solids that are made up of crystals
particles that are not arranged in a set pattern
where particles are loosely connected and can collide with and move past each other
a substance that flows
the result of an inward pull among the molecules of a liquid that brings the molecules of a surface together
a liquids resistance to flowing
has no definite shape or definite volume
What are molecules of a gas doing?
atoms and molecules are free to move independently, colliding frequently
change in state from a solid to a liquid
characteristic temperature of melting
What is happening to the molecules during melting?
the particles in the solid vibrate so fast that they break free from their fixed positions
change from a liquid to a solid
What is happening to the particles during freezing?
the particles in the liquid move so slowly that then begin to take fixed positions
change from a liquid to a gas
What is happening to the molecules during vaporization?
the particles in a liquid gain enough energy to move independantly, forming a gas
when vaporization only takes place on the surface of a liquid
occurs when a liquid changes to gas below its surface as well as at the surface
the temperature at which a liquid boils
the change of state from a gas to a liquid
What are the particles doing during condensation?
the particles in a gas lose enough thermal energy to form a liquid
occurs when the surface particles of a solid gain enough energy that they form a gas
What are the particles doing during sublimation?
particles of a solid do not pass through the liquid state as they form gas
