CORRECT PHYSICAL PROPERTIES WORKSHEET IN GC
Chemistry Notes: Physical properties 10/4/2023
physical property - a characteristic that you can observe or measure without changing the identity of the matter.
State - solid, liquid, gas
during changes of state, particle motion changes but the substance remains the same.
type of atoms not changed
molecules/chemical formulas not changed
Mass - amount of matter an object contains
volume - amount of space an object occupies
melting point - temperature at which a solid turns to a liquid
boiling point - temperature at which a liquid turns to a gas
density - ratio of mass per unit of volume of a substance
conductivity - how well a substance can conduct (conduct (carry along) electricty/heat
electrical conductivity
thermal conductivity
solubility - the ability of one substance (solute) to dissolve in another (solvent)
magnetism - a force of attraction between certain metals
Some properties are size dependent.
The measurement varies with the amount of matter
mass, volume, dimensions of size
these are properties of objects, not substances
