Boiling Point

The temperature at which the vapor pressure of a liquid is equal to the applied pressure, also the condensation point

Capillary Action

The drawing of a liquid up the inside of a small-bore tube when adhesive forces exceed cohesive forces, or the depression of the surface of the liquid when cohesive forces exceed the adhesive forces.

Secondary Voltaic Cells

Voltaic cells that can be recharged, original reactanats can be regenerated be reversing the direction of the current flow.

Ideal Gas Law

The product of pressure and the volume of an ideal gas is directly proportional to the number of moles of the gas and the absolute temperature.

Alkaline Battery

A dry cell in which the electrolyte contains KOH.

Electrolysis

Process that occurs in electrolytic cells.

Bonding Orbital

A molecular orbit lower in energy than any of the atomic orbitals from which it is derived, lends stability to a molecule or ion when populated with electron.

Acid

A substance that produces H+(aq) ions in aqueous solution. Strong acids ionize completely or almost completely in dilute aqueous solution. Weak acids ionize only slightly. Chemicals or substances having the property of an acid are said to be acidic.

Corrosion

Oxidation of metals in the presence of air and moisture.

Resonance
