What are the three primary states of matter? - ✔✔-Solid, Liquid, or Gas
What is the definition of a solid? - ✔✔-Substance that has definite size and shape. The molecules of a
solid have very little movement
What is the definition of a Liquid? - ✔✔-Incompressible substance with constant volume that assumes
the shape of its container. Molecules flow freely.
What is the definition of a Gas? - ✔✔-Compressible substance with no specific volume. It tends to
assume the shape of its container. Molecules move about most rapidly in this state.
What states of matter have the least and most mobility? - ✔✔-Solids have the least mobility. Gases have
the most mobility.
Definition of a vapor? - ✔✔-Gaseous state of a material that may normally be a solid or a liquid.
Definition of an Aerosol? - ✔✔-Microscopic particles that may be a solid or a liquid.
Definition of Dust? - ✔✔-Airborne solid particles that may be 0.1-50 microns in diameter.

One atmosphere is how many mmHg? - ✔✔-760 mmHg
This pressure is normally found at sea level
What is a Bar? - ✔✔-Unit of pressure measurement, not part of SI
One Bar = 100,000 Pascals
What is Torr? - ✔✔-Unit of pressure measurement not part of SI
Measured as 1/760 of a standard atmosphere
