|
solid |
The state of matter in which materials have a definite shape and a definite volume. |
|
|
liquid |
The state of matter in which materials have a definite volume but not a definite shape. |
|
|
gas |
The state of matter in which materials have neither definite shape nor definite volume. |
|
|
kinetic energy |
The energy a object has due to its motion. |
|
|
plasma |
The state of matter in which materials exist at extremely high temperatures. |
|
|
Bose-Einstein |
The state of matter in which materials exist at extremely low temperature (near -273K). |
|
|
pressure |
The result of a force distributed over an area. |
|
|
absolute zero |
The temperature of 0 Kelvin. |
|
|
Charles's Law |
A law that states that the volume of gas I directly proportional o its temperature in kelvins if the pressure and the number of particles remain constant. |
|
|
Boyle's Law |
A law that states that the volume of a gas is inversely proportional to its pressure if the temperature and the number of particles remain constant. |
|
|
phase change |
The reversible physical change that occurs when a substance changes from one state of matter to another. |
|
|
endothermic |
A type of change in which the system absorbs energy from its surroundings. |
|
|
heat of fusion |
The amount of energy required for a substance to melt. |
|
|
exothermic |
A type of change in which the system releases energy to its surroundings. |
|
|
vaporization |
The endothermic phase change in which a substance changes from a liquid to a gas. |
|
|
heat of vaporization |
The amount of energy required for a substance to change rom a liquid to a gas. |
|
|
evaporation |
An endothermic, vaporization phase change in which a substance changes from a liquid to a gas BELOW the substance's boiling point. |
|
|
vapor pressure |
The pressure caused by he collision of vapor with the walls of the container. |
|
|
condensation |
The phase change in which a substance changes from a gas or vapor to liquid. |
|
|
sublimation |
The phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first. |
|
|
deposition |
A phase change in which a substance changes from a gas or vapor directly into a solid without first changing to a liquid. |
