Sublimation is the process by which a substance changes from solid state directly to vapour state. Example : dry ice, naphthalene balls etc.

Any solid may be sublimed if its temperature and pressure are below its triple point. For example, if you were to freeze water into ice and cool it further and then reduce the pressure, you could get ice to sublime.

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 process in which a solid changes directly to a gas is called sublimation. It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Solid carbon dioxide changes directly to the gaseous state. …

Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.

Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

When dry ice “melts” it releases carbon dioxide gas which could build up inside an airtight cooler and make it explode. Users must adhere to special usage instructions and safety precautions when using dry ice.

When dry ice is added to water, it sublimes to carbon dioxide gas rapidly because the solution’s temperature is warmer than the dry ice (-78.5 C° or -109.3 F°). This gas can be observed as bubbles or clouds above the solution.

Putting dry ice in a boiling pot of water on the stove is one of the fastest ways to dispose of it. If you don’t want to do that then a bowl or bucket of warm water can do the trick. Over time the dry ice will make the water cold and may even freeze it.

To dispose of dry ice, place it in a well-ventilated area at room temperature; the remainder of the ice will sublimate away. Never dispose of dry ice in a trash can, chemical waste container or other garbage/waste can.
