copper, or silver and copper, etc. -- Soft solder, a solder fusible at comparatively low temperatures; as, plumbers' solder, consisting of two parts lead and one part tin, is a soft solder.

s) See under Gravity. -- Specific heat (Physics), the quantity of heat required to raise temperature of a body one degree, taking as the unit of measure the quantity required to raise the same weight of water from zero to one degree; thus, the specific heat of mercury is 0.033, that of water being 1.000. -- Specific…

n on a surface of highly heated metal, it rolls about in spheroidal drops or masses, at a temperature several degrees below ebullition, and without actual contact with the heated surface, -- a phenomenon due to the repulsive force of heat, the intervention of a cushion of nonconducting vapor, and the cooling effect of…

equal to, or not greatly above, that of the atmosphere. -- Saturated steam, steam at the temperature of the boiling point which corresponds to its pressure; -- sometimes also applied to wet steam. -- Superheated steam, steam heated to a temperature higher than the boiling point corresponding to its pressure. It can n…

ies of heat. The unit most commonly employed is the amount of heat necessary to raise the temperature of one gram or one pound of water from zero to one degree Centigrade. See Calorie, and under Unit.

An instrument for recording simultaneously the pressure and temperature of a gas; a combined thermograph and barograph.

An instrument for automatically recording indications of the variation of temperature.

An instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompained by proportional changes in their volumes or dimensions.

An instrument for recording graphically the variations of temperature, or the indications of a thermometer.

The estimation of temperature by the use of a thermometric apparatus.
