Magnetic fields in vibrating-wire instruments have strengths of 1 T [14]. The heat capacity of liquid ammonia over a temperature range between 50 °F and 80 °F is given by the following expression: Cp = 0.487 + 2.39 x 10-4T Btu Where Cp is in and T is in F. Ibm "F a) What is the value of Cp at 80 °F. The properties tabulated are pressure (P), density (ρ), enthalpy (H), entropy (S), isochoric heat capacity (Cv), isobaric heat capacity (Cp), speed of sound (u), viscosity (η), thermal conductivity (λ), and static dielectric constant (D). Heat capacity c p: 47.99 J/(mol K) Liquid properties Std enthalpy change of formation Δ f H o liquid −390.76 kJ/mol Standard molar entropy S o liquid? Heat capacity at constant volume Cv. As for nitrogen, it is readily available… well, all around us…     Cp = heat capacity (J/mol*K) Ind. Read : The Shomate Equation will yield the most accurate estimate of the enthalpy change for an ideal gas. Uses polynomial obtained from CHERIC. Ammonia, with its four atoms, is an incredibly simple molecule: Despite this simplicity, its large-scale industrial production from its constituent elements — nitrogen and hydrogen — was, and remains, a great scientific challenge. Enthalpy of sublimation.     Cp = heat capacity (J/mol*K) Follow the links above to find out more about the data However, NIST makes no warranties to that effect, and NIST J/(mol K) Heat capacity c p? At ambient pressure and temperature the isobaric specific heat, C P, of ammonia is 2.2 [kJ/kg K] or 0.52 [Btu/lb °F] = [cal/g K], while the isochoric specific heat, C V, is 1.6 [kJ/kg K] or 0.39 [Btu/lb °F] = [cal/g K]. until midnight EST on Monday December 28. binary mixtures and chemical reactions, SRSD 2 – Web Thermo Tables (WTT), "lite" edition, SRSD 3 – Web Thermo Tables (WTT), professional edition, SRD 156 – Clathrate Hydrate Physical Property Database. [all data], Zander and Thomas, 1979 The nominal world-wide capacity of its manu­ facture for the year 1993-1994 is estimated to be in excess of 116 million metric tons. Chern.
