| Term | Definition |

| Adhesion | two different particeles together. two different substances together |
| Cohesion | A force holding same type of particles together. (ex) water molecules-water molecules |
| Expansion | Molecules heat up and move farther apart. Which makes it expand. |
| Contraction | Molecules slow down and move closer together which makes it move in and get smaller |
| Energy | Temp of molecules is the amount of energy that they have |
| Heat | Transfer of thermal energy between substances that are at different temperatures |
| Thermometer | To test the heat of temp. or kinetic energy |
| Variable | To effect eh expirement of the lab. can be controlled, others not. |
| hypothesis | an educated guess of the lab |
| observations | using your 5 sense. to collect data |
| conculsions | explanations from your observations. why something happend |
| diffusion | movement or mixing of one molecule to another. (EX) food coolring |
| air pressure | pressure casued by air molecules, greater temperatues |
| temperature | particles in a substance . measure of amount of Kinetic energy |
| inferences | to explain or interpret |
| molecule | made upof 2 or more atoms. one or more jpined together |
| matter | tiny particels, atoms and molecules |
| implode | to burst inward |
| condensation | change in stae of gas to liquid |
| evaporation | liquid to gas at the surface of liquid. have enough energy to break from cohesion |
| sublimation | insantaneous change of matter: solid-gas |
| melting | temp change from solid to lquid |
| boiling | a specific temperature that then changes into a gas |
| freezing | molecules slow down and they freeze. (EX) water to liquid, the withdrawal of heat to change something from a liquid to a solid |
| Kinetic energy | matter made up of tiny particles and those particles arein constant |
| convection current | transfer heat in a liquid or a ga. (ex) heat rises cooled sinks down |
| solid | molecules slow down, tightly packed, hit harder, cause more friction, and vibrate in place, no definiate shpae or volume |
| liquid | No definiate shape, takes the shape of object, molecules slide by eachother |
| Gas | Molecules move vioently, no shape or volume |
| Adhesion | two different particeles together. two different substances together |
