The specific heat discussed until now is a thermal property that can be understood as the change in the internal energy per degree temperature change of 1 mol (or 1 kg) substance under constant volume. As mentioned previously, this part of internal energy associated with sensible heat is stored...
Helium has a higher specific heat ratio (γ) and a specific gas constant (R), which allow the gas to accelerate to much higher velocities than nitrogen, and therefore it is capable of accelerating metal particles to much higher velocities. This can be measured by the speed of sound at the...
A high-temperature adiabatic calorimeter has been developed to measure the constant-volume specific heat capacities (cV) of both gases and liquids, especially fluids of interest to emerging energy technologies. The chief design feature is its nearly identical twin bomb arrangement, which allows accurate...
Due to constant volume conditions, the heat evolved in the reaction corresponds to the internal energy change.This is the internal energy change for the specific amount of reactant undergoing combustion. ΔErxn per mole of a particular reactant is obtained by dividing the value by t...
The inter granular voids of the sample charge are then filled with water, and the weight (m) of the added inter granular water is determined. A target specific gravity value (SG) is selected for the fluidized oil sand ore. The volume of additional water, 螖V, to add to a sample ...

of time and then released. The device, which came to be known as theLeyden jar, consisted of a stoppered glass vial or jar filled with water, with a nail piercing the stopper and dipping into the water. By holding the jar in the hand and touching the nail to the conductor of an ...
Depending on the amount of water these two values may differ considerably (see e.g. [36] and Chapter Wood in this volume). At the end of this section an essential caveat should be kept in mind. Caloric values less than 17.6 kJ/g afdw should be considered with suspicion. Carbohydrates ...
where α is the coefficient of linear expansion and ζ is the isothermal compression rate. By introducing the parameter Γ, which is defined as (3.2.17)Γ=3αζCυυ Eq. (3.2.16) becomes (3.2.18)p=pc(υ)+ΓυCυT where Cυ is the specific heat capacity at constant volume. Assumin...
