|
Absolute humidity |
Actual mass or content of water in a measured volume of air, usually expressed in grams per cubic meter or pounds |
Grams per cubic meter or pounds |
|
|
Acoustics |
The science of sound |
|
|
|
Adhesive Forces |
Attractive forces between two different kinds of molecules |
|
|
|
Ammeter |
An instrument for measuring the strength of an electric current in terms of amperes |
|
|
|
Amorphous Solids |
Solid, such as glass or margarine, in which the constituent atoms & molecules are arranged in a fashion that is not rigid. In contrast, the constituent particles of crystalline solids are more rigidly arranged |
|
|
|
Ampere |
The standard unit of measurement of electric current |
|
|
|
Archimedes Principle |
When an object is submerged in a fluid, it will be buoyed up by a force equal to the weight of the fluid that is displaced by the object |
|
|
|
Atomic Theory |
The concept that all matter is composed of submicroscopic atoms that are,in turn, composed of protons, electrons, and neutrons. Chemical element is identified by the number of protons in its atoms |
|
|
|
Atom |
Smallest division of an element that exhibits all the properties and characteristics of that element, including neutrons, electrons, and protons. The number of protons in the nucleus of every atom of a given element is the same and it's called the atomic number |
|
|
|
Avogadro's number |
Number of particles (e.g. Atoms or molecules) in one mole of a particular substance. It had been determined to be approximately 6.02 x 1023 mole-1 |
|
|
|
Boiling point |
Temperature at which a liquid begins to turn to gas.. For water at 1 atm: 100°C, 212°F, or 373°K absolute |
|
|
|
Boltzmann universal gas constant |
A fundamental physics constant named for Ludwig Boltzmann, who determined its value as being equivalent to the ratio of the universal gas constant to Avogadro's number. It has a value of 1.380662 x 10(-23) joules per Kelvin |
|
|
|
Buoyancy |
When an object is immersed in a fluid, it appears to weigh less than it does in air. |
|
|
|
Celsius |
Temperature scale in with 0° the freezing point of water and 100° is the boiling point of water at sea level |
|
|
|
Cohesive forces |
Attractive forces between like kinds of molecules |
|
|
|
Compounds |
A substance composed of two or more elements chemically combined in definite proportions, that cannot be separated by physical means |
|
|
|
Condensation |
Change of state from gas to liquid, such as with water vapor condensation |
|
|
|
Critical point |
The critical temperature and the critical pressure of a substance |
|
|
|
Critical pressure |
The pressure above which a material cannot exist as a gas |
|
|
|
Critical temperature |
Temperature below with your material cannot exist of a gas |
|
|
|
Diffusion |
Physical process of Atoms or molecules that tend to move from an area of higher concentration or pressure to an area of lower concentration or pressure |
|
|
|
Dipole-Dipole interactions |
The interaction of equal & opposite electrical charges |
|
