density of materials

gas
-
particles have lots of energy and they are free to move, travel in random directions
-

displacement method
-
- put in eureka can filled with water. the water is displaced by object and will transfer to measuring cylinder
- use formula to work out density
for regular objects:
measure width, length and volume using ruler and then use formula
density of a liquid
pour 10cm of water into a measuring cylinder, recording the mass and volume each time until total volume of liquid is in cylinder

specific latent heat
when a substance is melting/ boiling putting in energy means increasing internal energy. but energys used for breaking intermolecular bonds rather than raising temp.
