Most chemists relied on the familiar thermodynamics of heat ( enthalpy ) of Berthelot, Ostwald, and Van t Hoff, and the calorimetric school.
12.
A mathematical correction factor, known as the phi-factor, can be used to adjust the calorimetric result to account for these heat losses.
13.
The calorimetric constant will vary from instrument to instrument, and can be determined by analyzing a well-characterized sample with known enthalpies of transition.
14.
Heats of formation can be determined experimentally though calorimetric studies; however, calculated enthalpies are more commonly used due to the greater ease of acquisition.
15.
In this scenario, the transition temperature is known as the " calorimetric ideal glass transition temperature " " T " 0c.
16.
For studies of hydration at very high relative humidities, a special modification of the method of sorption calorimetry the desorption calorimetric method was developed.
17.
For a calorimetric material substance; it is of the essence of heat transfer that it is not mediated by the externally defined forces variables that define work.
18.
For example, values of the Gibbs energy obtained from high-temperature equilibrium emf methods must be identical to those calculated from calorimetric measurements of the enthalpy and entropy values.
19.
In 1990, barely a year after the original announcement of excess energy in an electrochemical cell by Pons and Fleischmann, Oriani corroborated this finding using a sophisticated calorimetric technique.
20.
In each repetition of a cyclic process, the net work done by the system, measured in mechanical units, is proportional to the heat consumed, measured in calorimetric units.
