Stuve et al. [78STU/FER] also reported the results of a limited set of drop calorimetry experiments (402.9 to 1001.5 K). The authors fitted an equation to the experimental enthalpy differences such that the heat capacity values meshed smoothly with the value obtained tfom adiabatic calorimetry for 298.15 K. The authors indicated that their equation was applicable, within 0.6 per cent for temperatures between 298 and 1200 K. As discussed below, NiS04 decomposes towards the upper end of this temperature range, and extrapolation of the heat capacities to 1200 K does not seem justified. Conversion of the equation from calorie to joule units leads to ... [Pg.194]

The heat capacity C , thermodynamic functions S , -(G -Hj.)/T, H"- Hj., and the equilibrium constant K for the formation of PH as an ideal gas from the elements have been calculated for a standard-state pressure of 1 atm and tabulated for 298.15 K and between 0 and 6000 K at 100 K intervals [2, 4]. The JANAF data with T = 298 K are based on early spectroscopic data [7, 8] and semiempirical estimates for Dq and the electronically excited states [3]. In the third edition of the JANAF Tables [1], the old values were only converted to Joule units and to a standard pressure of 0.1 MPa. In the Russian compilation [4], values for a reference temperature T = 0 K are given that are based on a partition function established by using spectroscopic data for the X a A, A rij states [9,10] and theoretical data for the b and c 11 states [3, 11]. Selected values from [4] are ... [Pg.22]

Joule—Unit of energy used to describe a single pulsed output of a laser it is equal to 1 watt-second or 0.239 calories. [Pg.491]

Caution If you keep in mind that the AG are given in kj, that is, in 1000 joule units, you will get... [Pg.87]

Joule Unit of measurement for energy or work (one joule = one coulomb flowing across a potential of 1V for 1 s)... [Pg.48]

Regardless of the category or end application, price is always a consideration. Although a premium price can be leveraged for aerospace and defense applications, the end users will require a budgetary restraint. For the best price comparison within various technology platforms, it is typically helpful to express all metrics in terms of the cost unit ( ) per power (Watts ) and energy (Joules ) units.

The joule (unit of energy) is the work done when the point of application of 1 newton is displaced a distance of 1 meter in the direction of the force. [Pg.577]

The tabulated value for is expressed in joule units. Here, we are writing the positive sign explicitly to emphasize the fact that AS increases. [Pg.162]

Note that we have converted the enthalpy of vaporization into joule units. [Pg.167]

The coulomb units cancel, as does one of the meter units. The joule unit is in the denominator of the denominator, which ultimately places it in the numerator. Evaluating the numerical expression, we find that... [Pg.225]

In the next to last expression, one of the joule units has been broken down into its fundamental units to illustrate how these units cancel. [Pg.354]

The 2iry term comes from the term in the numerator. One of the joule units cancels directly, and using the fact that J = kg m /s, we see that the second joule unit cancels the s unit in the numerator and the kg-m unit in the denominator. The only remaining unit, K in the denominator of the denominator, comes up to the numerator. We have... [Pg.644]

If the joule unit is unsupported in the cross-linking chamber being used, calculate the required intensity by the equation W=J/s (W watt, J joule, s second). [Pg.41]
