Particle Model Of Matter Flashcards
Describe the particles in a liquid
- loosely arranged
- slip and slide over each other
- weaker forces between them
- small spaces between them
Describe the particles in a solid
- closely packed
- vibrate against each other
- strong forces holding them together
- small spaces between them
Describe the particles in a gas
- no particular arrangement
- move very fast
- extremely weak forces between them
- very big spaces between them
Explain why phenolphthalein turns pink
Particles of ammonia gas moved through the tiny spaces between the particles of the dialysis membrane into the test tube
Why will a blown up balloon collapse over time
The atoms of the ballon have tiny spaces between them particles of air move through these spaces and out of the ballon and the ballon collapses
Explain the heating of a solid
- solids particles will absorb the heat energy and vibrate faster and faster
- particles will have so much energy they will overcome the forces of attraction
What is the process of heating a solid called
Melting
Explain the phases of heating a liquid
- particles will slip and slide over each other
- particles of liquid will move further and further apart
What is heating a liquid called
Evaporation
Explain the phases of cooling a gas
- particles lose heat energy and move slower and slower
- forces of attraction become stronger pulling the particles closer together
What is cooling a gas called
Condensation
Explain the phases of cooling a liquid
- particles lose heat energy and move slower and slower
- forces of attraction become stronger, pulling the particles closer together
What is cooling a liquid called
Solidification
What is heating a solid turning directly into a gas
Sublimation
