WebSep 3, 2024 · 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. The melting point is the temperature at which a solid changes into a liquid. WebNaphthalene, a common ingredient in mothballs, also sublimes easily. Arsenic can also sublime at high temperatures. Sublimation requires additional energy and is an endothermic change. The enthalpy of sublimation can be calculated as the enthalpy of fusion plus the enthalpy of vaporization .

Sublimation - Introduction, Process and Examples of Sublimation

WebAug 10, 2024 · Sublimation Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO 2) sublimes, appearing to gradually disappear without ever forming any liquid. Websublimation, 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 phenomenon is the result of vapour pressure and temperature relationships.
