The total energy in all of the particles in an object.
The faster the particles move, the warmer the matter can get.
Matter Changes state when thermal energy is added (+) or removed(-)
Examples of thermal energy are stoves and matches.
What is thermal energy?

That all substances have a boiling point and a melting point.
All matter can change state (not just water) by adding (+) or removing(-) Thermal Energy.◦ Adding (+) Thermal Energy causes molecules to
speed up.◦ Removing(-) Thermal Energy cause molecules to
slow down. Every substance has a different melting
point and boiling point
What does our Table Tell Us?

Why do you think different substances have different melting points and boiling points?◦Brainstorm ideas with a partner in your
notebook on pg 51
They all have a different arrangement of molecules that react differently to added thermal energy
Melting Point & Boiling Points of different Elements

1) The _melting point is when the particles of a solid break free from their fixed positions.2) The phase change from a liquid to a gas is called vaporization, the two ways a liquid can vaporize are __Evaporation_ and _boiling___.3)_Evaporation__ occurs when only surface particles vaporize (change into a gas).4) _Boiling__ occurs when vaporized water molecules form bubbles below the surface and rise (occurs at the surface and in the liquid).
