Pure substance |
either a compound or an element, cannot be physically separated, has the same composition throughout. |
|
|
Element |
A substance that cannot be broken down into any other substances by chemical or physical means. |
|
|
Compound |
Two or more elements combined using chemical bonds. Example: water H2O, Carbon dioxide CO2 |
|
|
Mixtures |
Two or more substances together in the same place, but not chemically bonded. |
|
|
Heterogeneous Mixture |
A mixture where the composition is not uniform. Example ranch, and salsa |
|
|
Homogenous Mixture |
The substances are evenly distributed with a uniform composition. Example sugar water and salt water. |
|
|

A change in matter that produces a new substance or alters the identity of a substance. |
|
|

measure of the force of gravity on an objects mass. |
|
|

|
|
Temperature |
A measure of the average energy of motion of the particles of a substance. |
|
|
Pressure |
The force of the total push on the walls of a gas's container, divided by the area of the wall of the container. Pascals |
|
|
Boyle's Law |
At a constant temperature, when pressure is increased, the volume decreases. P1V1=P2V2 |
|
|
Charle's Law |
At a constant pressure, when temperature is increased, the volume increases. V1/T1=V2/T2 |
|
