Estimates of the difference between thermodynamic temperature and the International Temperature Scale of 1990 in the range 118 K to 303 K.
Using exceptionally accurate measurements of the speed of sound in argon, we have made estimates of the difference between thermodynamic temperature, T, and the temperature estimated using the International Temperature Scale of 1990, T90, in the range 118 K to 303 K. Thermodynamic temperature was estimated using the technique of relative primary acoustic thermometry in the NPL-Cranfield combine...
متن کاملSolubility of Cis, Cis-Muconic Acid in Various Polar Solvents from 298.15 K to 348.15 K
The present work concerns with an investigation on the solubility of cis,cis-muconic acid dissolution in different polar solvents by characterizing and modeling the dissolution as a function of temperature. Water, ethanol, 2-propanol and acetic acid have been investigated as solvents in the range temperatures from a 298.15 to 348.15 K. Owing to the absence of cis,cis-muconic acid solubility...
متن کاملTemperature (K)
The Mg-doped CuGeO3 system, Cu1-xMgxGeO3, undergoes a first-order phase transition at a critical concentration xc between an antiferromagnetic (AF) state on dimerized lattice (D-AF, i.e. coexistence of AF and SP order parameters) and an AF Néel state on undistorted uniform lattice (U-AF). Previous magnetic susceptibility measurements showed xc = 0.023 while a recent neutron scattering study rep...
متن کاملThermodynamic Temperatures of the Triple Points of Mercury and Gallium and in the Interval 217 K to 303 K
National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 We measured the acoustic resonance frequencies of an argon-filled spherical cavity and the microwave resonance frequencies of the same cavity when evacuated. The microwave data were used to deduce the thermal expansion of the cavity and the acoustic data were fitted to a temperature-pressure surface to deduce zeropressu...
متن کاملEffects from the charm scale in K + → π + νν̄
We consider contributions to the rare decay K+ → π+νν̄ which become nonlocal at the charm scale. Compared to the leading term, such amplitudes are suppressed by powers of mK/m 2 c and could potentially give corrections at the level of 15%. We compute the leading coefficients of the subleading dimension eight operators in the effective theory below the charm mass. The matrix elements of these ope...
