Week 6: How the properties of matter relate to their chemical structure Flashcards
a characteristic of a substance that can be observed or measured without changing the identity of the substance
physical property
Physical properties of matter include:
color, hardness, malleability, solubility ,electrical conductivity, density ,melting points, and boiling points.
can be a very useful parameter for identifying an element
density
helps determine how an element (especially a metal) might be used
hardness
somewhat unique identifiers, especially of compounds
melting and boiling points
The temperature which causes liquid to boil
boiling point
The concentration of a substance. Increases as its temperature decreases
density
Helps determine how an element (especially a metal) might be used
hardness
The temperature which causes solids to melt
melting point
A characteristic of a substance that can be observed or measured without changing the identity of the substance
physical property
properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter
chemical properties
the ability of matter to combine chemically with other substances
reactivity
he ability of matter to burn. When matter burns, it combines with oxygen and changes to different substance
flammability
properties that can be measured or observed without matter changing to an entirely different substance
physical properties
States of matter include:
liquid, solid, and gaseous states
