How could you construct a model to represent motion of the particles in solids liquids and gases

The atoms in solids don't move a lot, so you could draw them close together with (( )) to show them vibrating.

Atoms in liquids move more than solids, but not as much as gasses. You could draw them further apart with longer arrows.

Atoms in gases move the most, so draw the atoms further apart than liquids and have the arrows be longer than liquids as well.

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
