|---|---|---|---|---|---|
| Matter | Any thing with mass and volume.
🗑
|
||||
| Mass | -How much "stuff" is in something; measured in grams.
🗑
|
||||
| Volume | The amount of space something takes up; measured in ml or cm2; cauculated length x width x height, poured in a graduated cylinder, or displacment
🗑
|
||||
| Freezing | When liquid becomes a solid (doesn't have to be cold.)
🗑
|
||||
| Evaperation | Liquid to gas without boiling; happens because faster moving particles hit the slow ones causing an energy change giving the slow particle enough energy to go to a gas. This can happen at any temperature
🗑
|
||||
| Condensation | Gaseous phase, to the liquid phase; cause is a loss in energy. Particles slow down.
🗑
|
||||
| Sublimation | When solid becomes a gas (w/out becoming a liquid.)
🗑
|
||||
| Deposition | Gas to solid phase (w/out becoming a liquid.)
🗑
|
||||
| Three Phases | Solid, liquid, & gas.
🗑
|
||||
| Weight | A measurement of gravity.
🗑
|
||||
| Characteristics of a gas | Empty space between particles; fast particles, spread out particles, made of particles.
🗑
|
||||
| Properties | Characteristics of materials that scientist use to describe, help identify, and distinguish materials from each other.(Ex: color, boiling/ freezing pointe.) odor.)
🗑
|
||||
| Molecules | Atoms can be combined to make a compound particle;
🗑
|
||||
| Pure substance | When a substance is made up of one kind of particle(O2) or molecule (H2O)
🗑
|
||||
| Mixture | When a substance is made up of at least 2 different substances.
🗑
|
||||
| Boiling point | The pointe at which the liquid goes to a gas because of temperature; while boiling the molecules will move farther apart but hold its original shape.
🗑
