|
vaporization |
The conversion from liquid to a gas or vapor |
|
|
evaporation |
vaporization that occurs at the surface of a liquid that is not boiling |
|
|
vapor pressure |
the measure of force exerted by a gas above a liquid |
|
|
boiling point |
the temperature at which the vapor pressure of the liquid is just equal to the external pressure of the liquid. |
|
|
normal boiling point |
the boiling point of a liquid at a pressure of 101.3 kPa |
|
|
What factors determine the physical properties of a liquid? |
disruptive motions of particles in a liquid and the attractions among these the particles |
|
|
What is the relationship between evaporation and kinetic energy? |
Only those molecules with a certain minimum kinetic energy can escape from the surface of the liquid. |
|
|
When can dynamic equilibrium exist between a liquid and its vapor? |
In a system at constant vapor pressure, a dynamic equilibrium exists between the vapor and the liquid.This is because the rate of evaporation of liquid equals the rate of condensation to vapor. |
|
|
Under what conditions does boiling occur? |
When a liquid is heated to a temperature at which particles throughout the liquid have enough kinetic energy to vaporize, the liquid begins to boil. |
