what is thermal energy
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.

    • (I will hand this out)
what does our table tell us
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
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
Phase Change Wrap-up ??: Answer on pg. 52

1) The _melting pointis 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).
