|---|---|---|---|---|---|
| Phase change | When a substance takes in or gets rid of energy. There is a change from one phase to another (solid, liquid, or gas)
🗑
|
||||
| Melting | Change from solid to liquid.Arrangement of molecules becomes less orderly, more random
🗑
|
||||
| Vaporization | Change from liquid to gas. Molecules are spread out, all over
🗑
|
||||
| Condensation(Liquification) | Change from gas to liquid. Examples: Dew, fog, steam on the mirror after shower
🗑
|
||||
| Freezing | Change from liquid to solid. Arrangement of molecules becomes more orderly
🗑
|
||||
| Sublimation | Change from solid to gas. Examples: dry ice, “old ice”, and moth balls undergo sublimation
🗑
|
||||
| Deposition | Change from gas to solid
🗑
|
||||
| What are the characteristics of a solid? | Has a definite shape and definite volume
🗑
|
||||
| How are the particles in a solid arranged? | Particles are packed close together
🗑
|
||||
| What are the characteristics of a liquid? | Takes the shape of its container and has a definite volume
🗑
|
||||
| How are the particles in a liquid arranged? | Particles are more random
🗑
|
||||
| What are the characteristics of a gas? | Fills its container (does not have a definite shape) and does not have a definite volume
🗑
|
||||
| How are the particles in a gas arranged? | Particles are not in any formation
🗑
|
||||
| Matter | Substance that has mass and takes up space.
🗑
|
||||
| Plasma | Plasma is a gas with electricity or electrons (ions)Most common state of matter in the universe
🗑
|
||||
| BEC-Bose Einstein Condensate | 5th state of matter,Very cold
🗑
|
||||
| Kinetic Molecular Theory | This theory explains why matter behaves as it does. All particles of matter are in constant motion.
🗑
|
||||
| Absolute Zero | (-273 Celcius or 0 kelvin)- motion of molecules STOPS!
🗑
|
||||
| Kinetic Energy | Energy of an object due to the motion of its particles or molecules.
🗑
|
||||
| 3 factors that affect gas pressure | Temperature, Volume, Number of particles
🗑
|
||||
| Boyle's Law | The effects of the pressure and volume of a gas are opposite. So, if volume increases, pressure decreases.
🗑
|
||||
| Charles Law | The volume of a gas increases at the same rate as the temperature of the gas.
🗑
|
||||
| pressure | force over area
🗑
