Particle Model Flashcards
1
Q
What equation links density, mass and volume?
A
Density = mass/volume
rho not P for density
2
Q
Describe the solid state
A
- fixed shape
- cannot flow
- difficult to compress
- strong inter-molecular bonds
- generally dense
- particles vibrate slowly around a fixed point
3
Q
Describe a liquid state
A
- can change shape
- can flow
- not easy to compress
- generally quite dense
- particles move around each other slowly
- weak inter-molecular bonds
4
Q
Describe a gas state
A
- shape can change
- can flow
- low density
- easy to compress
- no inter-molecular forces
- particles move around quickly with random velocities
