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.
