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 |
