Sublimation is, in fact, a universal phenomenon exhibited by all solids at temperatures below their triple points. However, sublimation is a scientifically and technically useful phenomenon only when the vapor pressure of the solid phase is high enough for the rate of vaporization to be rapid. Four of such solids include iodine, sulphur, naphthalene, and even dry ice (solid carbon dioxide).

What safety precautions should be taken when using radioactive substances?
you need to stay about 3-4 feet away from the substance.
Sublimation is the process of turning a liquid into a gas?
No. So, you haven't had company for a while, and when they arrive you haven't any ice, although all 3 ice trays were full just a few weeks ago! Sublimation occurs when a solid transpires directly into a gas.
What are four types of mixtures?
Mixtures are substances that are made by physical combination of one or more substances and none of the constituent elements are changed. The basic classification of mixtures is into homogeneous and heterogeneous substances. They can also be further divided under these two categories in to solutions, dispersions or colloids.Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures. A homogeneous mixture in which there is both a solute and solvent present is also a solution. Heterogeneous mixtures include fine sand or silt in water.Rate This Answer
