Heat capacity in proteins.
Heat capacity (Cp) is one of several major thermodynamic quantities commonly measured in proteins. With more than half a dozen definitions, it is the hardest of these quantities to understand in physical terms, but the richest in insight. There are many ramifications of observed Cp changes: The sign distinguishes apolar from polar solvation. It imparts a temperature (T) dependence to entropy an...
متن کاملHeat Capacity in Bits
The temperature T may be expressed as the rate of energy increase per unit increase in the state uncertainty under no-work conditions. The consequences of such a choice for heat capacities are explored. I show that the ratio of the total thermal energy E to kT is the multiplicity exponent ~log–log derivative of the multiplicity! with respect to energy, as well as the number of base-b units of m...
متن کاملExperiment 3. Heat-capacity Ratios for Gases
In considering the theoretical calculation of the heat capacities of gases, we shall only be concerned with perfect gases. Since Ĉp = Ĉv + R for an ideal gas (where Ĉp and Ĉv are the molar quantities Cp/N and Cv/N), our discussion can be restricted to Cv. The number of "degrees of freedom" for a molecule is the number of independent coordinates needed to specify its position and configuration. ...
متن کاملHeat capacity of protein folding.
We construct a Hamiltonian for a single domain protein where the contact enthalpy and the chain entropy decrease linearly with the number of native contacts. The hydration effect upon protein unfolding is included by modeling water as ideal dipoles that are ordered around the unfolded surfaces, where the influence of these surfaces, covered with an "ice-like" shell of water, is represented by a...
متن کاملIncreasing Cooling Towers Heat Capacity by Flue Gas Introduction
In this paper the changes in the heat capacity of cooling towers has been investigated as a result of injecting combustion products of boilers. In the tower, the air is re-heated through mixing with hot flue gas after passing through the heat exchangers. As a result of this process, the draft of the cooling tower is increased. The additional produced draft depends on the ambient temperature and...
