| Question | Answer |
|---|---|
| Sublimation | solid to a gas |
| Deposition | gas to a solid |
| Movement of solid particles and gas particles | vibrate, zoom |
| How do you know if a molecule is polar or non-polar? What are the corresponding number values? | Electronegativity .3 and down are non-polar and .3 and up are polar |
| The stronger the intermolecular forces, the _____ the vapor pressure and the ______ the boiling or melting points | lower, higher |
| Why would water boil at a higher temperature at Death Valley ( below sea level) and at a lower temperature in Denver | higher pressure = higher B.P boiling point |
| Vapor Pressure | as temperature increases the amount of vapor in a closed container increases |
| how are vapor pressure and temperature related? | increase in temp causes vapor pressure to rise |
| What is volatility? Which is more volatile a polar or a non polar compound? | measure of a substance propensity to vaporize nonpolar is more volatile |
| What is conduction | transfer of heat by direct contact |
| what is convection | transfer of heat by current actual fluid motion |
| what is radiation? | heat transfer by electromagnetic waves |
| OK is known as what? | absolute zero |
| What happens at this temperature? | motion stops |
