States of Matter

QuestionAnswer
Phase change When a substance takes in or gets rid of energy. There is a change from one phase to another (solid, liquid, or gas)
Melting Change from solid to liquid.Arrangement of molecules becomes less orderly, more random
Vaporization Change from liquid to gas. Molecules are spread out, all over
Condensation(Liquification) Change from gas to liquid. Examples: Dew, fog, steam on the mirror after shower
Freezing Change from liquid to solid. Arrangement of molecules becomes more orderly
Sublimation Change from solid to gas. Examples: dry ice, “old ice”, and moth balls undergo sublimation
Deposition Change from gas to solid
What are the characteristics of a solid? Has a definite shape and definite volume
How are the particles in a solid arranged? Particles are packed close together
What are the characteristics of a liquid? Takes the shape of its container and has a definite volume
How are the particles in a liquid arranged? Particles are more random
What are the characteristics of a gas? Fills its container (does not have a definite shape) and does not have a definite volume
How are the particles in a gas arranged? Particles are not in any formation
Matter Substance that has mass and takes up space.
Plasma Plasma is a gas with electricity or electrons (ions)Most common state of matter in the universe
BEC-Bose Einstein Condensate 5th state of matter,Very cold
Kinetic Molecular Theory This theory explains why matter behaves as it does. All particles of matter are in constant motion.
Absolute Zero (-273 Celcius or 0 kelvin)- motion of molecules STOPS!
Kinetic Energy Energy of an object due to the motion of its particles or molecules.
3 factors that affect gas pressure Temperature, Volume, Number of particles
Boyle's Law The effects of the pressure and volume of a gas are opposite. So, if volume increases, pressure decreases.
Charles Law The volume of a gas increases at the same rate as the temperature of the gas.
pressure force over area
