What is thermal energy? 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 does our Table Tell Us? 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

Melting Point & Boiling Points of different Elements 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

Phase Change Wrap-up ??: Answer on pg. 52 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).
