Sublimation was used to refer to the process in which a substance is heated to a vapor, then immediately collects as sediment on the upper portion and neck of the heating medium (typically a retort or alembic), but can also be used to describe other similar non-laboratory transitions.

2025年1月24日 · Sublimation, in physics, conversion of a substance from the solid to the gaseous state without its becoming liquid. An example is the vaporization of frozen carbon dioxide (dry ice) at ordinary atmospheric pressure and temperature.

2023年4月15日 · When a solid is converted directly to a gas, the process is known as sublimation. The reverse processes are freezing and deposition, respectively. … Melting is the conversion of a solid to a liquid.

We can define sublimation as the transition of a substance from the solid phase to the gaseous phase without changing into the liquid phase. This process is an endothermic phase transition that occurs at a temperature and pressure below the triple point of the substance.

2020年1月9日 · Sublimation is the transition from the solid phase to the gas phase without passing through an intermediate liquid phase. This endothermic phase transition occurs at temperatures and pressures below the triple point.

Sublimation is the transition of a substance directly from the solid phase to the gas phase without passing through the intermediate liquid phase under specific conditions of temperature and pressure.

2023年6月5日 · Sublimation is the process by which a substance transitions directly from the solid phase to the gaseous phase, bypassing the liquid phase. Sublimation is a physical process that takes place when the pressure of the surrounding atmosphere is insufficient to maintain a substance in its liquid state.

Sublimation is how a solid becomes a gas without becoming a liquid first. It happens when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Most substances can sublimate only at low pressure. Many can sublimate in space. Sometimes snow sublimates.

Sublimation is a type of phase change that takes place when a solid turns directly into a gas, skipping the liquid phase. The opposite of sublimation is vapour deposition. The term "sublimation" only applies to a physical change of state and not to the transformation of a solid into a gas during a chemical reaction.

Sublimation is the term for a phase change that proceeds directly from the solid phase to the vapor phase without first making the transition to the liquid state. The most common example of sublimation is that of solid carbon dioxide, CO 2, or "dry ice".
