Definition
the conversion of liquid to a gas or a vapor |
|
|
Term
|
Definition
vaporization that occurs at the surface of a liquid that is not boiling |
|
|
Term
|
Definition
a measure of the force exerted by a gas above a liquid in a sealed container; a dynamic equilibrium exists between the vapor and the liquid |
|
|
Term
|
Definition
describes the gaseous state of a substance that is generally a liquid or solid at room temperature |
|
|
Term
|
Definition
the temperature at which the vapor pressure of a liquid is just equal to the external pressure on the liquid |
|
|
Term
|
Definition
the boiling point of a liquid at a pressure of 101.3 kPa or 1 atm |
|
|
Term
what determines the physical properties of liquids? |
|
Definition
disruptive motions of particles and attractions among particles |
|
|
Term
why do liquids have a definite volume? |
|
Definition
the attraction between particles in liquids |
|
|
Term
liquid particles are much closer together so... |
|
Definition
liquids are more dense than gases |
|
|
Term
do most water particles have enough kinetic energy to become gas? |
|
Definition
|
|
Term
what does heat do to liquids |
|
Definition
increases the kinetic energy of particles and some are able to escape the surface |
|
|
Term
liquids evaporate into... |
|
Definition
|
|
Term
gas/ vapors condense into... |
|
Definition
|
|
Term
what is the equilibrium between of a liquid contained at a constant pressure |
|
Definition
(evaporation)vapor and (condensed)liquid |
|
|
Term
what rises when the temperature of a contained liquid rises? |
|
Definition
|
|
Term
vapor pressure indicates... |
|
Definition
how volatile (or how easy it evaporates) a liquid is |
|
|
Term
what is vapor pressure measured with? |
|
Definition
|
|
Term
what happens when the kinetic energy of liquid molecules heat up enough to vaporize? |
|
Definition
|
|
Term
what effects the boiling point of a liquid? |
|
Definition
altitude( atmospheric pressure) |
|
|
Term
does vapor have less stored energy than liquid? |
|
Definition
no, it has more (so vapor burns are more severe than liquid burns) |
