Presentation transcript:

Ionic Compounds have highest melting points… b/c they have the strongest bonds due to crystal lattice VS

Melting Points Strongest ( highest): Ionic Bonding ( cation-anion) Hydrogen Bonding ( H & NOF) Dipole-Dipole ( polar) Lowest ( weakest) Dispersion ( nonpolar)

Viscosity 1. What was the difference between the two? 2. What do you think viscosity means?

Kinetic Molecular Theory matter

Elevation and Atmospheric Pressure ↑ Elevation = ↓ Atmospheric Pressure b/c less gas particles =less collisions =  P Sea Level more gas particles = more P

More gas particles = More collisions= More pressure

Evaporation/ Condensation Equilibrium

to make something boil added Energy/Heat is addedOr EXTERNAL changed the EXTERNAL pressure is changed Boiling : Vapor Pressure = External Pressure

Temp vs Heat HeatTemperature Definition energy transfer due to a temp difference Measure of kinetic energy, Measure of atom movement Additional 2 objects same temp = no heat Absolute zero = no atom movement Symbol:QT Unit:JoulesKelvin, Celsius or Fahrenheit
