So the change in enthalpy to go from solid to a gas directly (sublimation) at some temperature is equal to the sum of the enthalpies associated with going from a solid to a liquid (fusion) and going from a liquid to a gas (vaporization) at other temperatures.hy is the enthalpy of sublimation is equal to the sum of enthalpy of fusion and enthalpy of vaporization?

Thus hydration is one of the main causes of electrolytic dissociation in aqueous solutions. The formation of crystal hydrates and the hydration of molecules and ions in solutions are special cases of solvation, that is, the addition of the solvent molecule. Hydration also includes processes leading to the binding of water through absorption forces. In biological systems hydration involves the addition (binding) of water to various substrates in the organism. The water, which enters into the hydration shells formed on hydration, constitutes the principal quantity of the so-called bound water of a cellâs protoplasm. Many biological processes are connected with hydration.
