3. These colligative properties are…

4. The pressure within a solution – pushing out because it wants to evaporate! Atmospheric pressure usually prevents this from happening by pushing back down. But – when vapor pressure and atmospheric pressure are equal, it boils!

5. Point at which vapor pressure (pushing up) equals atmospheric pressure ( Heat is only needed to get vapor pressure up high enough to equal the downward push of atmospheric pressure! pushing down).

6. Temperature is a measure of kinetic energy of particles. Low temp. = low kinetic energy Particles slow down, get close together and solidify kinetic energy of solids

8. What kinds of solutes affect colligative properties?

10. Ionic Solutes dissociate into: NaCl  MgCl 2  Na 3 PO 4  2 moles of ions 3 moles of ions 4 moles of ions 1 Na +1 + 1 Cl -1 1 Mg +2 + 2 Cl -1 3 Na +1 + 1 PO 4 -3

11. The solutes below are placed into water. What happens to these solutes as they begin to dissolve? C 6 H 12 O 6  C 12 H 22 O 11  **They dissociate one molecule at a time! 1 C 6 H 12 O 6 1 C 12 H 22 O 11 1 mole of particles
