a. The heat content of a body as measured on a definite scale based on
some observable phenomenon; e.g., the expansion of mercury on heating.
See also:absolute temperature; Celsius; centigrade;
critical temperature; Fahrenheit; Kelvin temperature scale;
Rankine scale. Webster 3rd
b. A degree of hotness or of coldness measured on one of several arbitrary
scales based on some observable phenomenon; e.g., the expansion of mercury
on heating. The degree of a material substance that is a linear function
of the kinetic energy of the random motion of its molecules. The degree of
a vacuum that depends upon the density of the radiant energy within it.
Abbreviations and symbols, temp; T; t; T; t. CF:absolute zero
Webster 3rd
A numerical value indicating the relation between a change in temperature
and a simultaneous change in some other property (e.g., solubility).
Specif., the factor a in the equation Rt = R0 (1 at), in
which Rt equals the resistance of a conductor at t degrees C, and R
0 equals its resistance at 0 degrees C.
Syn:positive temperature coefficient
Colors shown to the eye by incandescent bodies at different temperatures.
Temperature at which condensation of water occurs; a saturation
temperature. Hartman, 2
a. The rate of change of temperature with distance in a specified
direction. Also called lapse rate. AGI
b. A curve showing the temperature at different distances from the hot
face, in a refractory wall.
The measurement of temperature in boreholes by use of a delicate
thermometer that will record temperature anomalies of as much as 7 degrees
F (3.9 degrees C) for thin coal seams in coal measures according to the
thermal conductivity of the rocks concerned. Sinclair, 3
A portable unit consisting of a thermistor sensing element, 6-V power
supply, amplifier, and recorder. The recorder is geared to a drum
containing an electrical cable to which the bead is fastened. When the
bead is lowered into the water, the paper on the recorder is moved
accordingly. Depth is measured by the amount of wire paid out. This device
is used in shallow water, particularly in lakes. Hunt
temperature-regulating equipment
Any equipment used for heating and cooling the rectifier together with the
devices for controlling and indicating its temperature.
Coal Age, 1
For normal measurement, 0 degrees C (regarding gas properties). For
thermodynamics and physical properties, either 18 degrees C or 25 degrees
C, as defined in each stated case. Pryor, 3
Reinforcement introduced into a concrete slab or other member to minimize
any cracks arising from shrinkage or from temperature stresses.
Hammond
Stress in a structural member due to a rise or fall of temperature.

a. A geophysical prospecting method that measures either (1) temperature
anomalies in boreholes or (2) temperature trends and concentrations along
the ground surface. For example, a temperature survey across a salt dome
may give peak values in the central area, due to the high thermal
conductivity of the buried salt mass. See also:temperature logging
Nelson
b. Measurement of temperature in drill holes. An absolute accuracy of
about 0.05 degrees C and a precision of about 0.005 degrees C can be
obtained. Maps of isotherm surfaces can be constructed that help to detect
anomalies in geologic structure or subsurface ground-water conditions.
AGI
In brickmaking, (1) moistened and worked to the proper consistency, as
clay for bricks or molding, and (2) capable of being cut with ease, as
bricks made of such clay. Standard, 2
Steel that has been hardened and subsequently tempered by a second lower
heating. Fay
One who or that which tempers; specif., a machine for mingling and
thoroughly working potter's clay, brick clay, mortar, plaster, or other
materials. Standard, 2
A term applied to alloys that increase in hardness when heated after rapid
cooling; also to the operation of producing this. Also called artificial
aging; distinguished from aging or age hardening, which occurs at
atmospheric temperature. Both processes are covered by the term
precipitation hardening. CTD
See:furgen
A furnace for heating articles in the process of tempering.
Standard, 2
A machine for giving large steel plates a uniform and thorough tempering
without permitting them to bend or buckle; usually by pressing them
between hot masses of iron, or by firmly clamping them between jaws or
plates while immersing them in a tempering bath. Standard, 2
