Enthalpy of Vaporization - Physical Model For Vaporization

Physical Model For Vaporization

A simple physical model for the liquid-gas phase transformation has been proposed recently. It is suggested that the energy required to free an atom from the liquid is equivalent to the energy needed to overcome the surface resistance of the liquid. The model allows calculating the latent heat by multiplying the maximum surface area covering an atom (Fig. 1) with the surface tension and the number of atoms in the liquid. The calculated latent heat of vaporization values for the investigated 45 elements agrees well with experiments.

Famous quotes containing the words physical, model and/or vaporization:

    The physical world is meaningless tonight
    And there is no other.
    Wallace Stevens (1879–1955)

    She represents the unavowed aspiration of the male human being, his potential infidelity—and infidelity of a very special kind, which would lead him to the opposite of his wife, to the “woman of wax” whom he could model at will, make and unmake in any way he wished, even unto death.
    Marguerite Duras (b. 1914)

    On the vaporization and the centralization of the Self. All is there.
    Charles Baudelaire (1821–1867)
