States of matter Flashcards
1
Q
arrangement in solid
A
- arranged regularly and packed closely
- the particles are only vibrate about a fixed point
- the particles have strong force of attraction between them so they cannot move around
2
Q
arrangement in liquid
A
- arranged randomly
- the force between particles are less effective
3
Q
why liquid are less dense than solid
A
the particles are still mostly touching but some gaps have appeared
4
Q
arrangement in gas/air
A
- no force of attraction between particles
- the particles in gas are move out randomly in all direction
5
Q
solid to gas
A
sublimation
6
Q
gas to solid
A
deposition
7
Q
deposition
A
condensing
8
Q
liquid to gas
A
boiling / evaporating
9
Q
solid to liquid
A
melting
10
Q
liquid to solid
A
freezing
11
Q
what is difference between evaporating and boiling
A
evaporation occurs at any temperature
does not show bubbles
boiling occurs at fixed temperature (100’C)
shows bubbles
12
Q
diffusion
A
the spreading put of particles in gas or liquid
13
Q
what is diffusion
A
spreading out of particles from where they are at a high concentration to where they are low concentration
