---|---|---|---|---|---|
altitude | vertical distance, or elevation, above sea level
🗑
|
||||
boil | change from liquid to gas
🗑
|
||||
boiling point | the temperature at which boiling occurs
-at sea level, the boiling point of water is 100 °C ( 32 °F )
-water boils at lower temperature at higher altitudes because air pressure is lower there
🗑
|
||||
freeze | change from liquid to solid
🗑
|
||||
freezing point | the temperature at which freezing occurs
- at sea level, the freezing point of water is 0 °C ( 32 °F )
🗑
|
||||
gas | a phase in which matter has no definite shape or volume
🗑
|
||||
gas properties | will expand to fill any container; con be compressed; molecules relatively far apart and move freely
🗑
|
||||
water vapor | water in the gas phase
🗑
|
||||
liquid | a phase in which matter has definite volume but no definite shape
🗑
|
||||
liquid properties | will take the shape of a container but cannot expand or be compressed; molecules in a liquid move randomly but stay close to one another
🗑
|
||||
melt | change from solid to liquid
🗑
|
||||
melting point | the temperature at which melting occurs
- at sea level, the melting point of ice is 0°C ( 32 °F )
🗑
|
||||
phase | a state of matter with certain physical properties
-solid, liquid, and gas phases occur naturally on earth
- plasma is a phase found in stars
🗑
|
||||
solid | a phase in which matter has a defenite shape and volume
🗑
|
||||
solid properties | will retain the same shape and volume in any container; atoms are held in a rigid structure and cannot move freely
🗑
|
||||
ice | water in the solid phase
🗑
|
||||
thermal energy | energy in the form of heat
🗑
|
||||
vaporization | rapid change from liquid to gas
🗑
|
||||
condensation | change from gas to liquid
🗑
|
||||
sublimation | change from solid to gas
🗑
|
||||
evaporation | slow change from liquid to gas
🗑
|
||||
deposition | change from gas to solid
