Phases of Matter
Phases of Matter Solids: particles: tightly packed in orderly pattern particles can’t move very much vibrate back & forth
Gases: Particles: far apart move rapidly from place to place
Liquids: in between solids & gases particles have more movement than solids but are close together
Why do liquids & solids exist? What holds them together?
Kinetic Energy atoms & molecules in constant motion Temperature = measure average KE of particles in sample of matter
If temperature ↑, the average KE↑ , then average KE If temperature
Temperature vs. Phase gas & solid at same temp have same average KE but particles in these 2 phases move very differently
Types of motion Gases can move from place to place – they can tumble – they can shake
Solids can only vibrate -in a back and forth motion
Liquids can vibrate but have very hindered movement moving place to place or tumbling particles can move a little bit bump into neighbors
What is a phase change? A transition between phases There Can are 6 you name them?
1. solidification l → s 2. melting s → l 3. Vaporation l → g 4. condensation g→ l 5. sublimation s→ g 6. deposition g→ s
Melting solid →liquid
source Boiling liquid →gas
Deposition gas→solid Sublimation solid → gas
Condensation gas→liquid
Freezing liquid→solid Sublimation gas→solid
Phase Changes When substance goes from gas to condensed phase (s or l), what happens? particles get closer together and their motion slows down
Phase Changes When substance goes from solid to liquid or gas, what happens? particles move farther apart and their motion increases
