states of matter
Question | Answer |
---|---|
what are the states of matter? | solid, liquid, gas,plasma,and bose-einstein condensate |
matter is organized based on | shape changes and volume changes |
definate | wont change when the matter is moved to a different container or location. |
definate does NOT mean... | the properties can never change |
variable | the property changes when you change the container or location of the matter. |
solids definate____ shape definate _____ volume | same, same |
liquids variable_____ shape definate ____ volume | changes, same |
gasses variable ___ shape variable _____ volume | changes, changes |
plasma includes ___% of the universe | 99% |
plasma only exists at | very high temperatures (lightning, sun, florecent lights) |
Bose-einstein condensate happens at_____ degrees and all atoms act like___________ | absolute zero (-273 degrees celcius) and atoms act like they are the same partial. |
kenitic theory of attraction explain____ | the behaviors of solids liquids and gasses |
kenetic theory___ | all particles are in constant motion |
solid has ____attractive force | strong and particles vibrate around a fixed location. |
gas particles are_________ | in constand random motion and unaffected by forces of attraction and collisions with other particles |
changes in phase are___ | reversable physical changes |
melting to? | freezing |
evaporation to? | condensation |
sublimination to? | deposition |
temperature ________ change during a phase change | does not |
during phase changes energy is either _______ or _________ | absorbed or released. |
endothermic | absorbing energy |
exothermic | releasing energy |
melting | less orderly particles of matter |
sublimination | solid into gas vapor |
depostition | gas vapor into solid |
vaporization | liquid into gas and less orderly particles of matter |
condensation | gas into liquid more orderly particles of matter. |
heat of vaporization | amount of energy required to change a substance from a liquid to a gas |
evaporization | liquid to gas takes place at surface of a liquid. lower temp than boiling. |
boiling | `temp increases and the water molecules move faster and faster |
boiling | water is less dense than liquid water, bubbles of water vapor quickly rise to the surface. when the bubbles reach the surface they burst and release the water vapor into the atmosphere |
boiling point depends on | elevation |
the ___ the elevation the lower the boiling point. | higher but it takes longer to cook. |
