| Question | Answer |
|---|---|
| what are the arrangements of particles within a solid | particles are very closely packed, arranged in a regular pattern, particles vibrate but to not move place to place |
| describe the arrangement of particles in a liquid | particles are closely packed, not arranged in a regular patter, particles move place to place |
| particles in a gas | particles are far apart, not arranged in any pattern, particles move rapidly from place to place |
| equation for density | P= m/v p= kg/m^3 m= kg v= m^3 |
| calc | 500kg/m^3 |
| why do solids have high densities | particles are packed closely together, they have lots of mass for their volume |
| why do liquids have high density | particles are closely packed, they have a lot of mass for their volume |
| why do gases late a low density | particles are very far apart, they have a small mass for their volume |
