where is a function of the temperature T and a typical wood dimension L and has units of time. The typical wood dimension is roughly the smallest value of (,, /) which are the radial, tangential and longitudinal dimensions respectively, in inches, with the longitudinal dimension divided by ten because water diffuses about 10 times more rapidly ...
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.
The form of the cooled surface often is a so-called cold finger which for very low-temperature sublimation may actually be cryogenically cooled. If the operation is a batch process , then the sublimed material can be collected from the cooled surface once heating ceases and the vacuum is released.
Outgassing is a challenge to creating and maintaining clean high-vacuum environments.NASA and ESA maintain lists of materials with low-outgassing properties suitable for use in spacecraft, as outgassing products can condense onto optical elements, thermal radiators, or solar cells and obscure them.
Solid carbon dioxide sublimes rapidly along the solid-gas boundary (sublimation point) below the triple point (e.g., at the temperature of −78.5 °C, at atmospheric pressure), whereas its melting into liquid CO 2 can occur along the solid-liquid boundary (melting point) at pressures and temperatures above the triple point (i.e., 5.1 atm, − ...

Non-stick coatings tend to degrade over time and are susceptible to damage. Using metal implements, harsh scouring pads, or chemical abrasives can damage or destroy cooking surface. Non-stick pans must not be overheated. The coating is stable at normal cooking temperatures, even at the smoke point of most oils. However, if a non-stick pan is ...
