The process uses the science of sublimation, in which heat and pressure are applied to a solid, turning it into a gas through an endothermic reaction without passing through the liquid phase. [citation needed] In sublimation printing, unique sublimation dyes are transferred to sheets of “transfer” paper via liquid gel ink through a ...
In thermodynamics, the enthalpy of sublimation, or heat of sublimation, is the heat required to sublimate (change from solid to gas) one mole of a substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP). It is equal to the cohesive energy of the solid.

A typical phase diagram.The solid green line applies to most substances; the dashed green line gives the anomalous behavior of water. In thermodynamics, the triple point of a substance is the temperature and pressure at which the three phases (gas, liquid, and solid) of that substance coexist in thermodynamic equilibrium. [1]
H sub, the standard enthalpy of atomization (or sublimation) of solid lithium. IE Li, the first ionization energy of gaseous lithium. B(F–F), the standard enthalpy of atomization (or bond energy) of fluorine gas. EA F, the electron affinity of a fluorine atom. U L, the lattice energy of lithium fluoride.
Miniature Créches. These tiny nativity scenes feature the traditional manger scene. Rather than each figure being its own piece, as in many nativity sets, the miniatures are a single cohesive ...
The entities -- including 13 Russian and 11 Chinese ones, were targeted by the Commerce Department for a host of reasons, including support for Russia's chemical and biological weapons programs ...
There are a number of methods for calculating the sublimation pressure (i.e., the vapor pressure) of a solid. One method is to estimate the sublimation pressure from extrapolated liquid vapor pressures (of the supercooled liquid), if the heat of fusion is known, by using this particular form of the Clausius–Clapeyron relation: [9]
