characteristic prp.

characteristic properties, density, phase changes...

characteristic properties differences between substances density, Melting point, freezing point, boiling point, condensation…
density how much space something takes up- mass/volume
phase change transitions between states of matter , pressure and temp can cause it to occur
melting point:: <------ freezing point ------>
condensation:: <------ boiling point ------>
liquid no fixed volume, molecules not tightly packed, medium energy
pressure makes things take up less room and become less dense
solid fixed volume, molecules tightly packed, low energy
gas no fixed volume, molecules loosely packed, high energy
sublime solid--->gas
condensation gas--->liquid
