What do you mean by Clausius-Clapeyron equation?
The Clausius Clapeyron equation is a way of describing a discontinuous phase transformation between two phases of matter of a single constituent, named after Rudolf Clausius and Benoît Paul Émile Clapeyron. A straight line does not exist between a liquid’s temperature and its vapour pressure.
What are the application of Clausius-Clapeyron equation?
The Clausius–Clapeyron equation is used to do a comparative study of the properties of the clouds that form in planetary atmospheres.
What is the Clausius-Clapeyron equation and why is it important?
This form of the Clausius-Clapeyron equation has been used to measure the enthalpy of vaporization of a liquid from plots of the natural log of its vapor pressure versus temperature.
What are the limitations of Clausius-Clapeyron equation?
You cannot break even (i.e., one cannot return to the same energy state, because entropy, or disorder, always increases). You cannot get out of the game (i.e., absolute zero is unattainable because no perfectly pure substance exists).
What is Clausius-Clapeyron latent heat equation?
The left hand side is the rate of increase of vapour pressure with temperature, while S2 − S1 is equal to L/T, where L is the specific latent heat of vaporization. Thus we arrive at the Clausius-Clapeyron equation: dPdT=LT(V2−VL).
What is Clausius-Clapeyron coefficient?
The Clausius–Clapeyron relation, named after Rudolf Clausius and Benoît Paul Émile Clapeyron, is a way of characterizing a discontinuous phase transition between two phases of matter of a single constituent. …
How do you calculate heat of vaporization?
Use the formula q = m·ΔHv in which q = heat energy, m = mass, and ΔHv = heat of vaporization.
What is the C in Clausius-Clapeyron?
Representation of the Clausius–Clapeyron equation (p = pressure of the phase; T = absolute temperature; ΔH = molar enthalpy of the phase transition; ΔV = difference in the molar volumes of the two phases 1 and 2; c = integration constant; R = gas constant).
What is heat of vaporization in chemistry?
The heat of vaporization is defined as the amount of heat needed to turn 1g of a liquid into a vapor, without a rise in the temperature of the liquid.
