Light, Heat and electricity
how is the connection of atoms in gasses
in gasses the atoms are moving very rapidly
how is the connection of atoms in liquids
in liquids the atoms are moving more than solids but not as fast as in gasses
how is the connection of atoms in solids
in solids, the atoms are tightly packed so they are not moving very much
what state of matter allows for the most compression
gasses because the atoms are not bound together.
what state if matter allows for almost no compression
solids because the atoms are tightly packed together.
what is an element
the smallest particle of matter
whatis a compound
made up of a specific elements chemically combined
what are 3 characteristics of compounds
