characteristic properties, density, phase changes...
| Question | Answer |
|---|---|
| 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 |
