Using the transient hot-wire method, simultaneous measurements of the thermal conductivity, λ, and the heat capacity per unit volume, ρc p, were made for solid phases I and II of benzene (C6H6). Data were obtained over the temperature range 105 K to 375 K, and at pressures up to 2...
The Heat Capacity of Benzene Vapor. The Contribution of Anharmonicity The heat capacity of benzene vapor was measured at two or more pressures at each of five temperatures in the range 68° to 198°C; and values ofCpo, the he... DW Scott,G Waddington,JC Smith,... - 《Journal of Chemi...
The heat capacity and the heats and temperatures of fusion of 1,2,4‐trimethylbenzene have been determined experimentally. This substance exhibits two melting points: at 229.33±0.03°K and at about 224.2°K. The only solid phase having reproducible heat capacities was found to be the one havin...
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...
What is the heat capacity of a substance if it takes 5.2 kJ of heat to warm 597.8 g by 46.6°C? Heat Capacity: The heat capacity of a substance is a physical property of the substance that gives the amount of energy required to change the temperature...
Since m = ρV, the heat capacity of the sensible storage can also be written as follows: 4.11Q=ρVCvΔT Analogous to the definition of density, we can define the thermal density of a thermal storage medium by rearranging Eq. 4.11: 4.12QVΔT=ρCv Thermal storage density is an important...
Condensationofgas to liquidrequires removal rather than addition of heat; the latent heat evolved in condensation is −Δhv. Similarly, the latent heat evolved in freezing or solidification of liquid to solid is −Δhf. Latent heat is a property of substances and, like heat capacity, varies...
Thermodynamic Studies of Orientational Disorder in π-π Molecular Compounds: 1. Heat Capacities of Naphthalene-Tetracyanobenzene The heat capacity of the π-π molecular compound naphthalene-tetracyanobenzene has been determined from 5 to 300 K. A small anomaly was observed in the he... J Boerio...

As adsorbent the material is usually not a good conductor of heat, the residual heat will increase the overall temperature of the bed thereby lowering the designated working capacity of CO2. Similarly, during desorption stage, temperature of the bed may go too low thereby trapping part of the ...
