States Of Matter Flashcards
(10 cards)
1
Q
Arrangement + motion of particles in solid (3)
A
- regular pattern / tightly packed
- particles vibrating
- about fixed positions
2
Q
Particles arrangement in liquids + gases
A
- particles arranged randomly
- particles further apart in gas than liquid
3
Q
Why speed of sound in liquids is greater than in gases
A
- sound travels by vibrations
- vibrations are passed on more effectively because particles are closer together
4
Q
Motion of particles in solid
A
- no movement
- only vibration
- about a fixed point
5
Q
Motion of liquid particles
A
- particles can slide over each other
6
Q
Motion of gas particles
A
- move freely
7
Q
What happens during changes in state of matter
A
- bonds between particles are broken / weakened
8
Q
Liquid arrangement:
A
- random
- close together
9
Q
Why does KE stay constant during change of state
A
- temperature stays constant
- speed of particles stays constant
10
Q
temperature is directly proportional to kinetic energy of particles
A
