Just chemistry definitions.

Absolute zero

-the temp. of -273.16 C (-459.69̊ F) ; the hypothetical point at which all molecular activity ceases


-a reaction that causes a gas to phase into a liquid.


-G to S (opposite)


-temperatures below 32̊ F ; to harden into ice/change from a liquid to a solid form by loss of heat (congeal)


-Phasing from a solid to a liquid


-indefinite volume

Ideal gas

-a gas composed of molecules on which no forces act except upon collision with one another and with the walls of the container in which the gas is enclosed; a gas that obeys the ideal gas law

Kinetic molecular theory

a) The gas consists of very small particles, all with non-zero mass.
b) The number of molecules is so large that statistical treatment can be applied.
c) These molecules are in constant, random motion. The rapidly moving particles constantly collide with the walls of the container


-composed of atoms that move freely among themselves but do not tend to separate like those of gasses


-the exertion of force upon a surface by an object; force per unit area


-composed of atoms that do not move freely among themselves, and are tightly compacted into one space


-the temperature of -0 C and pressure of 1 atmosphere, usually take as the conditions when stating properties of gasses


-Phasing from a S to G
-Ex: Dry ice


-moderate in respect to temperature; not subject to prolonged extremes of hot or cold weather


-to change or cause to change into vapor/gaseous state as a result of extreme heat
-Phasing from a liquid to a gas
