The work described in this paper sets out to measure, to an accuracy of 4%, the total heat absorbed by nylon 6.6 at normal regain when it is heated from room temperature to temperatures in the range 6O–220°C. The method of measurement employs a sensitive yarn-flow calorimeter, which ...
The breaking mechanism of nylon-6 yarn is investigated, and the breakage of the yarn under simple tensile loading conditions is compared to that of a filament caused by the same loading. The simple model yarn consisting of seven filaments was prepared for this purpose. The yarn was ruptured ...
Enthalpy and specific heat of germanium dioxide at high temperaturesTsagareishvili, D ShGvelesiani, G G
The phase transition temperatures were determined by differential thermal analysis (DTA), while specific heat and enthalpy were calculated according to several mathematical equations. The results have shown that, due to tribomechanical treatment, certain changes in thermophysical and energetic properties of...
An experimental procedure was developed enabling the specific heat capacity and enthalpy of coal pyrolysis in the instantaneous state at a given temperature to be determined. It was used to measure the thermal properties of six coals and the mineral matter at temperatures up to 130...
1af) of the NaA zeolite and its cation exchanged samples, the thermodynamic parameters (enthalpy, entropy and specific heat), peak temperature, peak width, transition temperature, Debye velocity, Debye temperature, Debye wave vector, Fermi wave vector were calculated first and corresponding the most...

Online Air Specific Heat Calculator The calculator below can be used to estimate the specific heat of air at constant volum or constant pressure and at given temperature and pressure. The output heat capacity is given as kJ/(kmol*K), kJ/(kg*K), kWh/(kg*K), kcal/(kg*K), Btu(IT)...
Specific heat capacity refers to a material’s heat capacity divided by mass, which governs the amount of energy needed to raise the temperature of one gram by one degree Celsius (or one Kelvin).
