| All of the laws of thermochemistry follow from the fact that the enthalpy H of a substance is one of its properties. |
|
| The change in heat content of the products relative to the reactants in a chemical reaction is known as the change in enthalpy. |
|
| Greater energy savings and maintained comfort are achieved with enthalpy economizers, though they cost more to install and maintain. |
|
| However, the transmutational process remained a mystery to them, as humans struggled to explain it within terms of entropy and enthalpy. |
|
| The internal energy of a system, like the enthalpy, is a state property, so it is fixed when the state of the system is specified. |
|
| So, we can get useful work out of a system by reducing enthalpy or by increasing entropy. |
|
| The enthalpy change which occurs when a solid is melted is called the heat of fusion. |
|
| The basic laws of thermochemistry can be expressed in terms of the change in enthalpy. |
|
| This binding affinity is related to free enthalpy of the formation of the product of metal and ligand. |
|
| Despite the large increase in enthalpy and entropy, the free energy difference between the closed and open conformations is relatively small. |
|
| Studies with a whole body exposure did not show as strong effect of the enthalpy of the air on perceived air quality. |
|
| First, the volume change and the enthalpy change of the protein can be determined in time domain without temperature variation or solvent variation method. |
|
| The enthalpy, entropy, and free energy changes in the opening reaction of each basepair are determined from the temperature dependence of the exchange rates. |
|
| The change in Gibbs free energy equals the enthalpy change for the reaction minus the product of the absolute temperature and the change in entropy for the reaction. |
|
| With a fixed enthalpy drop per unit mass, the power output thus can only be controlled by varying the mass flow rate. |
|
| The inlet enthalpy is determined by the exit conditions of the steam generator and the exit enthalpy by the condenser pressure. |
|
| Manages the flow of external and return air, making reference to their enthalpy values. |
|
| The enthalpy and entropy of folding for the tropomyosin and troponin T peptides were determined from the change in ellipticity as previously described. |
|
| The positive correlations lend support to the claim that a coupling free energy may reflect a state in which enthalpy and entropy components compensate for each other. |
|
| First, second and third laws of thermodynamics, enthalpy and heat balances, entropy, free energy, and chemical equilibrium. |
|
|
|
| The information may not be directly applicable to bundle geometries with a large degree of flow and enthalpy imbalances. |
|
| Low enthalpy energy resources are currently being used in many communities across Europe to assist in domestic heating. |
|
| Heat transfer is the flow of enthalpy from matter at a high temperature to matter at a lower temperature, when they are brought together. |
|
| Compare it with Fig. 4 which shows the changed enthalpy of saturated steam at the higher pressure of 10 bar abs. |
|
| Due to the presence of a dipole, a polar molecule shows greater intermolecular forces and hence affects its vapor pressure, boiling point, enthalpy of vaporization, and solubility. |
|
| The second peak was attributed to a transition from one solid state to another with the transition temperature and molar enthalpy being designated by Tt and AH, respectively. |
|
| The Gibbs function approach allows the calculation of internal energy, entropy, enthalpy, potential enthalpy and the chemical potentials of seawater as well as the melting heat of ice and the latent heat of vapor. |
|
| Additional room air humidification is superfluous: In Winter, the outside air is humidified by means of the enthalpy recovery unit and the room air moisture is automatically controlled. |
|
| The result clearly proves the out-standing temperature and enthalpy reproducibility of this cost-effective differential scanning calorimeter even at the limits of the temperature range. |
|
| The measurements most useful for monitoring energy use are flow, temperature, humidity, calorific value, enthalpy and electrical quantities such as voltage and current. |
|
| The net thermal energy produced for the deaerator does not provide useful information because it is equal to the enthalpy of the water make-up minus any heat losses. |
|
| Gelatinisation temperatures and enthalpy reduced on acetylation and diminished further as the acetyl group increased. |
|
| The enthalpy level can be read from the enthalpy curve of the polymer as a function of the preheat temperature. |
|
| This allowed for the most accurate enthalpy changes to be calculated. |
|
| For gas turbines, the energy extracted from the fluid also can be expressed in terms of the enthalpy change, which for a gas is nearly proportional to the temperature drop across the turbine. |
|
| An enthalpy heat exchanger is capable of a lot more. |
|
| This classification shows that a part of the enthalpy rise can in principle be realized outside the extruder by using preheating equipment such as an oven or a hopper dryer. |
|
| The observed enthalpy as obtained by DSC is the mathematical sum of the enthalpies of all individual reactions occurring in the temperature range of measurement. |
|
| Enthalpy is more useful to chemists than energy when measuring the heat involved in chemical reactions. |
