- kinetic theory
- the theory that explains the behavior of gases at the molecular level
- ionization
- the amount of energy needed to remove an electron from a specific atom or ion in its ground state in the gas phase
- Boyle's law
- the volume of a gaas at constant temperature is inversely proportional to the pressure
- Neutralization
- between an acid and hydroxide base in which H+ and OH- react to form water
- pH
- the negative logarithm of the hydronium ion concentration of an aqueous solution
- precipitate
- An insoluble solid formed by mixing in solution the constituent ions of a slightly soluble solution.
- ideal gas
- a model that effectively describes the behavior of real gases at conditions close to standard temperature and pressure.
- molarity
- concentration unit

- can be dissolved in a solvent
- aqueous solution
- liquid solution
- boiling point
- point in which a liquid will boil
- van der waals
- An equation of state that extends the ideal gas law to real gases by inclusion of two empirically determined parameters, which are different for different gases.
- absolute zero
- the point in which nothing moves because it is completely frozen
- hydronium ion
- hydrogen ion covalently bonded to a water molecule
- titration
- analytical procedure used to determine the concentration of a sample by reactiong it with a standard solution
