Matter States

Solid liquid gas and changing states of matter

QuestionAnswer
cohesion The attractive force between like molecules
adhesion The attractive force between unlike molecules
surface tension The cohesive force of a liquid at the surface
capillary action The rise and fall of a liquid in a narrow tube or space
Boyle's Law Under a constant temperature, when the pressure of a gas goes up, the volume goes down
Charles's Law Under a constant pressure, when the temperature of a gas goes up, the volume goes up
Solid A state of matter where the substance has a definite shape and volume
Solid A state of matter where the substance's molecules are tightly packed and vibrate in place
Liquid A state of matter where the substance has a definite volume and indefinite shape
Liquid A state of matter where the substance's molecules are close together but move fast enough to be able to slide by each other
Gas A state of matter where the substance has an indefinite shape and indefinite volume
Gas A state of matter where the molecules move fast and freely
Melting A change in state from a solid to a liquid
Freezing A change in state from a liquid to a solid
Condensation A change in state from a gas to a liquid
Vaporization A change in state from a liquid to a gas
Sublimation A change in state from a solid to a gas
Melting Particles gain energy. The particles begin to move fast enough to overcome some attractions and begin to move.
Vaporization Particles gain energy. The particles begin to move fast enough to overcome the attractions and begin to move freely.
Condensation Particles lose energy. The particles begin to slow down enough and attract more to each other and begin to clump together.
Freezing Particles lose energy. The particles begin to slow down so much that the attraction overcomes motion and particles lock in place.
Sublimation Particles gain energy. The particles begin to move fast enough to completely overcome the attractive force that locks the particles in place and allows them to break free.
Melting/Freezing point of water 0 celsius (32 Fahrenheit )
Vaporization/Condensation point of water 100 celsius (212 Fahrenheit)
endothermic change A phase change involving a gaining of heat energy
exothermic change A phase change involving a loss of heat energy.
endothermic change melting, vaporization, sublimation
exothermic change freezing, condensation, desublimation
desublimation A change in state from a gas to a solid
boiling vaporization from within a liquid
evaporation vaporization from the liquids surface
polar molecule a molecule that is has electrically charged areas
uniqueness of water exists in all 3 phases naturally on earth; gets less dense when it freezes
crystalline solid A solid that has molecules that are arranged in an orderly repeating pattern
amorphous solid A solid that has molecules that are not arranged in an orderly repeating pattern
crystalline solid ice
amorphous solid glass
Boyle's law ex. push down on a bicycle pump and the pressure increases
Charles' Law ex. leave a balloon in the cold and it deflates
