We have made heat-capacity measurements on ethane films adsorbed on graphtie for coverages between n =1.3 and 3.7 layers and for temperatures between 65 and 95 K. Two phase transitions are observed in the vicinity of the bilayer melting point. We propose an interpretation for our results based...
When calculating mass and volume flow of a substance in heated or cooled systems with high accuracy - the specific heat (= heat capacity) should be corrected according values in the table below. Specific heat of Ethane Gas - C2H6 - at temperatures ranging 250 - 900 K : Ethane Gas - C2H6...
The CODATA Task Group on Thermophysical Properties is preparing a set of recommended values for the heat capacity, thermal expansion, and transport properties of key solids which are used in calibrating or checking measuring equipment. The present paper surveys selected data on heat capacity at consta...
The objective of this study was to determine the heat capacity and heat of dissociation of methane hydrates. A technique has been devised which circumvents the two major problems encountered in measuring gas hydrate heat capacity: the need to impose a mechanical pressure during the measurement and...
The heat capacity of 99.98 mole % pure chlorodifluoromethane has been determined from 16-230°K. A λ-type transition in the solid was observed at approximately 59°K. with a heat of transition of 16 ± 2 cal. The heat of fusion at the melting point, 115.73 ± 0.01°K., was found...
Isobaric Heat CapacityMeasurements of Liquid Methane,Ethane, and Propane by Differential Scanning Calorimetry at High Pressuresand Low Temperatures. A commercial differential scanning calorimeter (DSC)was adaptedto allow accurate isobaric heat capacity, cp, measurements of cryogenic, high-pressure liqui......
The specific heat - CPand CV- will vary with temperature. When calculating mass and volume flow of a substance in heated or cooled systems with high accuracy - the specific heat (= heat capacity) should be corrected according values in the figures and the table below. ...
4) ideal gas heat capacity 理想气体比热 1. Speed of sound, ideal gas heat capacity and the second acoustic Virial coefficient have been experimentally studied for 1,1,1 trifluoroethane (HFC143a),which is a new refrigerant to substitute chlorodifluoromethane(HCFC22) and/or dichlorodifluoro...
this chapter will present the significance of specific heat capacity, detailed experimental procedure, and thecpof composites, as well as the parent materials at the operating temperature range of AHP and AD systems. Finally, all the experimental data are analyzed rigorously and correlated with the ...
