|
Substances can have 3 states, name them.
|
They can be solid, gaseous or liquid.
|
|
|
Whats the kinetic molecular theory of Gases?
|
-Gas molecules are fort apart and do not interact much with each other.
-Gases are highly compressible, assumes shape and volume of container. |
|
|
Whats the kinetic molecular theory of Liquids?
|
-Liquid molecules are held close together, more than gas molecules but not so rigidly that the molecules cannot pass each other.
-Liquids are almost incompressible, assume the shape but not the volume of the container. |
|
|
Whats the kinetic molecular theory of Solids?
|
-Solid molecules are packed closely together, they're so packed they cannot pass each other.
-Solids are incompressible and have a definite shape and volume. |
|
|
Describe characteristics of gases.
|
No definite shape or volume, vapor, co-exist with solids and liquids, highly compressible, occupy full volume of container, when subjected to pressure reduce volume, always form homogeneous mixtures with other gases, only occupy 0,1% of container volume.
|
|
|
Describe characteristics of liquids.
|
Highly viscous, flows by sliding molecules over each other, the stronger the intermolecular force the higher the viscosity.
Surface tension, bulk molecules are equally attracted to neighbors, surface molecules are only attracted to bulk molecules they're therefore more packed together, surface tension is the amount of energy required to increase surface area of a liquid. |
