At pressures below 5.13 atm and temperatures below −56.4 °C (216.8 K; −69.5 °F) (the triple point), CO2 changes from a solid to a gas with no intervening liquid form. It is used primarily as a cooling agent but is also used in fog machines at theatres for dramatic effects.
15 Απρ 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.

8 Οκτ 2020 · Sublimation: Dry ice undergoes sublimation to change from solid carbon dioxide directly into carbon dioxide gas. Another example is the transition from ice directly into water vapor on a cold, windy winter day.
Examples include dry ice (solid carbon dioxide), naphthalene, and iodine. These substances have well-defined sublimation points: the temperatures and pressures at which they transition directly from a solid to a gas phase.
Sublimation is defined as a process in which solid converts into gas directly without converting into liquid. Any solid-vapour transition is called sublimation. Examples of sublimation are burning of camphor, iodine and naphthalene is really evaporation of a solid.
Evaporation - when a particle of a substance in the liquid state at the surface, has enough energy to change to the gas state and mix with air. Sublimation - a change of state of a substance from a solid directly to a gas; e.g. iodine.
