Term | Definition |
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. |
