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