Describe how thermal energy affects atoms within the 3 states of matter

The  thermal energy  affects  atoms within  the  3  states of matter  as below The three state  of matter that is solid, liquid  and  gases  expand  when heat is added.When  heat  is added to  a substance, the molecules  and atom  vibrate  faster.As  atom vibrate faster  space between  them  increases.The motion and spacing of particle  determine  the state of mater of the substance.The  end result of  increased  molecular motion  the molecule   expand and  take more space.On the other hand  when  heat   leave  all  substance, the  molecules   vibrate  slower.Atoms  can get  closer which result in  matter  contracting.
