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 specific heat of liquid water is 4.184 J/g, which is also 4.184 KJ/Kg. The calorie is a unit of heat defined as the amount of heat required to raise the temperature of 1 cm3 of water by 1˚C.Specific heat Specific heat is the heat capacity per unit mass. The specific heat ...
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...
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 ...

Calorimetric determination of the isothermal pressure effect on the enthalpy of the propane‐benzene system An isothermal throttling calorimeter system has been built for obtaining the effects of pressure on the enthalpy of liquids and vapors. The propane-benzene system has been studied at 200°0, 30...

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...
Some reasons for the unsuccessful observation of this transition have been discussed in relation to different molecular conformations in each solid phase. The thermal behavior of HAT-C8 has been compared with that of the benzene-core discotic mesogen having the same alkyl chains. A remarkable ...
