Molecules in Solids

In solids the molecules are very close. These molecules vibrate in place.

Density in States of Matter




The density's vary because the particles are spread differently in each of the states. For example, in solids the particles are tightly packed and therefore have a higher density. In a liquid the particles are only slightly farther apart, they are loosely packed, so the desity is still high but it is lower than a solids. Finally in gases the density is very low due to the particles that are very far apart. These particles are fast moving and spread far apart. How tightly or loosely the particles are arranged inside substances, determines the objects density.

High/Close Particles Lower/Loose Particles Very Low/Spread Particles

DENISTIES/PARTICLES

Solids

Solids have many physical properties:

-Definite shape
-Definite volume
-Close particles that vibrate in place
-Low energy/Low temperature
-High density

Examples of Solids Include:

-Ice


-Metals
