| Term | Definition |
|---|---|
| equillibrium | when a system is experiencing no net change |
| conduction | transfer of KE by direct contact of particles |
| energy transfer | the transfer of higher KE to lower to KE |
| KE | the energy of moving particles (the more movement the more energy) |
| Particles (molecules) | simplest part of a substance that is still that substance |
| collide | when two or more things hit each other (particles bouncing off each other) |
| dissolve | to incorporate one substance uniformly into another substance at the particle level |
| melting | change of state from solid to liquid |
| solid | state of matter with definite shape and volume |
| liquid | state of matter with definite volume but not shape |
| phase | a particular state of matter |
| melting point | the temperature at which a solid changes to a liquid (water 32 degrees F or 0 degrees C) |
| freezing point | the temperature at which a liquid changes to a solid (water 32 degrees F or 0 degrees C) |
| condensation | change from the gaseous to the liquid state of matter |
| evaporation | change of state from the liquid state to the gaseous state |
| vapor | a condensable gas (water vapor) |
| sublimination | change of state from solid phase directly to a gaseous state |
| deposition | when a gas goes directly to a solid state |
| phases of matter | solid, liquid, or gas |
| solute | substance present in the least amount (salt in salt water) |
| solvent | substance that does the dissolving (water in salt water) |
