The meaning of CLAPEYRON EQUATION is an equation relating to change of phase in a pure substance (as vaporization of a liquid) that gives the rate of change with temperature of the pressure at equilibrium between the phases in terms of the heat of transi
ΔT= change in temperature of water Before we try to understand the significance of the + and - signs, let us recall three main concepts of thermodynamics. The first law of thermodynamicsstates that the amount of energy in the universe is a constant; it only moves from the system to the...
The van 't Hoff equation (also known as the van 't Hoff isochore) in chemical thermodynamics relates the change in temperature (T) to the change in the equilibrium constant (K) given the standard enthalpy change (ΔHo) for the process. The equation was first derived by Jacobus Henricus ...
The meaning of GIBBS-HELMHOLTZ EQUATION is an equation in thermodynamics that is applicable to reversible isobaric chemical processes: the difference between the change in free energy and the heat of reaction equals the product of the absolute temperatur
1.a shift in temperature, humidity, or the like resulting from horizontal movement of an air mass (disting. fromconvection). 2.the horizontal flow of air, water, etc. [1905–10; < Latinadvectiō=advec-,variant s. ofadvehereto convey (ad-ad- +vehereto carry) +-tiō-tion] ...
The equations for the change in glass transition temperature with stretching are derived to test the criteria for glass transition, i.e., the iso-free volume, the iso-configurational entropy, and the iso-configurational energy assumptions. It was found that the second assumption explains the ...
The equation for molar specific heat is c = q/(nΔT), where c is the molar specific heat, q is the heat absorbed or released, n is the number of moles of the substance, and ΔT is the change in temperature. What are the units for molar specific heat?

The Freundlich equation states that, at a constant temperature, the amount of adsorbate bound per unit weight of adsorbent, Qe (adsorption efficiency of the adsorbent) is a logarithmic function of the residual concentration in the fluid phase at equilibrium, Ce. At low-solute concentrations, the ...
