In a substance that sublimes
WebA substance which sublimes is denoted by symbols as sub, subf or 3. The melting point of a substance which sublimes should be determined in a sealed capillary tube in order to prevent sample loss. This can be done in two ways. 1. In a simple method the open end of the packed tube can be heated inside a flame and sealed with tweezers or forceps. 2.

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. WebSublimation is a specialized change of state when a solid substance skips the liquid phase and moves directly into the gas phase. This occurs because the substance absorbs energy so quickly from the surroundings that melting never occurs. Examples of Sublimation: 1. "Dry ice" or solid carbon dioxide sublimes. 2.
