SCIENCE CHEM UNIT

IQWEST introductttion to chemistry

TermDefinition
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.
