chariteristic prp.
characteristic properties, density, phase changes...
Question | Answer |
---|---|
characteristic properties | differences between substances density, Melting point, freezing point, boiling point, condensation…a property that is always the same no matter how much of it you have |
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 | fixed volume, molecules not tightly packed, medium energy, no fixed shape |
pressure | makes things take up less room and become less dense, force per area |
solid | fixed volume, molecules tightly packed, low energy,fixed shape |
gas | no fixed volume, molecules loosely packed, high energy,no fixed shape |
sublime | solid--->gas |
states of matter | solid, liquid, gas |
sublimation::------> | deposition<------ |
deposition | gas--->solid |
chromatography | separation of mixtures by solubility and molecular weight |
solubility | how well something dissolves into something else |
distillation | the separation of a liquid by heating or cooling |
hydrogen bonding | apart of water molecules, when hydrogen is attracted to another type of atom like oxygen or nitrogen |
filtration | uses solubility to separate mixtures by a filter |
floatation | the separation of a mixture by the use of density |
