Relating to thermodynamics; caused or operated by force due to the application of heat. Thermodynamic function. See Heat weight, under Heat.

The science which treats of the mechanical action or relations of heat.

iminishes. If a small amount, h, of heat enters the body when its temperature is t in the thermodynamic scale the entropy of the body is increased by h . The entropy is regarded as measured from some standard temperature and pressure. Sometimes called the thermodynamic function. The entropy of the universe tends toward…

by the mechanical equivalent of heat divided by the absolute temperature; -- called also thermodynamic function, and entropy. -- Mechanical equivalent of heat. See under Equivalent. -- Specific heat of a substance (at any temperature), the number of units of heat required to raise the temperature of a unit mass of t…

oled by a water jacket (water-cooled) or by air currents (air cooled) to give the maximum thermodynamic efficiency and to avoid excessive friction or seizing.

A line upon a thermodynamic diagram so drawn as to represent the pressures corresponding to changes of temperature when the volume of the gas operated on is constant. -- I`so*chor"ic (#), a.

t angles to each other; monometric; regular; cubic. Cf. Crystallization. Isometric lines (Thermodynamics), lines representing in a diagram the relations of pressure and temperature in a gas, when the volume remains constant. -- Isometrical perspective. See under Perspective. -- Isometrical projection, a species of or…

he process of high milling for grinding flour. See under Milling. -- Reversible process (Thermodynamics), any process consisting of a cycle of operations such that the different operations of the cycle can be performed in reverse order with a reversal of their effects.
