Aug 23, 2024 · 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.
The term sublimation refers specifically to a physical change of state and is not used to describe the transformation of a solid to a gas in a chemical reaction. For example, the dissociation on heating of solid ammonium chloride into hydrogen chloride and ammonia is not sublimation but a chemical reaction.
Jan 9, 2020 · Sublimation Definition. 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 . Read More.
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.
Jun 5, 2023 · 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. The process of sublimation can be defined as ...
Apr 15, 2023 · Sublimation is the change of state from a solid to a gas, without passing through the liquid state. Deposition is the change of state from a gas to a solid. Carbon dioxide is an example of a material that easily undergoes sublimation.
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.
Jan 27, 2019 · Sublimation is the term for when matter undergoes a phase transition directly from a solid to gaseous form, or vapor, without passing through the more common liquid phase between the two. It is a specific case of vaporization.
The transition of solid-phase into gaseous phase is sublimation. The matter does not undergo a liquid phase during this phase transition, that is the solid directly turns into a gas. In the sublimation process, this reaction is an endothermic reaction.
Aug 11, 2020 · Sublimation is an analogous process to boiling, as it occurs when a compound's vapor pressure equals its applied pressure (often the atmospheric pressure). The difference is that sublimation involves a solid's vapor pressure instead of a liquid's.
