Naphthalene is a solid that sublimes at standard atmospheric temperature with the sublimation point at around 80 °C or 176 °F. At low temperature, its vapour pressure is high enough, 1 mmHg at 53 °C, to make the solid form of naphthalene evaporate into gas. On cool surfaces, the naphthalene vapours will … Zobacz więcej Sublimation is the transition of a substance directly from the solid to the gas state, without passing through the liquid state. Sublimation is an endothermic process that occurs at temperatures and pressures below a … Zobacz więcej Carbon dioxide Solid carbon dioxide (dry ice) sublimes everywhere along the line below the triple point (e.g., at … Zobacz więcej In ancient alchemy, a protoscience that contributed to the development of modern chemistry and medicine, alchemists developed a … Zobacz więcej Dye-sub printing is a digital printing technology using full color artwork that works with polyester and polymer-coated substrates. Also referred to as digital sublimation, the process is commonly used for decorating apparel, signs and banners, as … Zobacz więcej Sublimation is a technique used by chemists to purify compounds. A solid is typically placed in a sublimation apparatus and heated under Zobacz więcej The enthalpy of sublimation has commonly been predicted using the equipartition theorem.
