Intermolecular Force
Chapter 11: Definitions
| Term | Definition |
|---|---|
| Intermolecular forces | electrostatic forces that create bonds between molecules |
| Dipole- dipole attraction | when the negative charge of a polar molecule creates a bond with the positive charge of a polar molecule |
| London dispersion forces | ( Can be in both non-polar and polar); temporary induced dipole forces. |
| Hydrogen bonds | when you have an H+ atom and it is connected to the electronegative atom of the other molecule |
| Polarizability | how easy it is to disturb the electron cloud |
| AH^0 ( vap) | when one mole of liquid changes into a gas |
| AH^0(fusion) | when one mole of gas changes into a liquid |
| Critical Temperature | Temperature where we don't have a liquid nor a gas |
| Critical Pressure | Pressure required to liquify a gas beyond the critical point |
| Sublimation | When a solid turns to a gas |
| Fusion | when a solid turns to a liquid |
| Vaporization | when a liquid turns to a gas |
| Deposition | when a gas turns into a solid |
| Condensation | when a gas turns into a liquid |
| Freezing | when a liquid turns into a solid |
| Vapor pressure | pressure exerted by a vapor in equillibrium with its liquid or solid state. |
| vapor | a substance in the gas phase when the gas is not its most stable form |
