Dry ice means the solid form of carbon dioxide. It is commonly used for temporary refrigeration as CO 2 does not have a liquid state at normal atmospheric pressure ...
Dry ice seems so magical, and it is! Follow these rules when handling it to stay safe on Halloween however you use it: in drinks, punch bowls, and more.
Cloud seeding can be done by ground generators or planes [citation needed] This image explaining cloud seeding shows a substance – either silver iodide or dry ice – being dumped onto the cloud, which then becomes a rain shower. The process shown in the upper-right is what is happening in the cloud and the process of condensation upon the ...
Dry ice bombs are commonly made from a container such as a plastic bottle, water and dry ice. The bottle is partly filled with water. Chunks of dry ice are added and the container is closed tightly. As the solid carbon dioxide warms, it sublimates to gas and the pressure in the bottle increases.
Comparison of phase diagrams of carbon dioxide (red) and water (blue) showing the carbon dioxide sublimation point (middle-left) at 1 atmosphere. As dry ice is heated, it crosses this point along the bold horizontal line from the solid phase directly into the gaseous phase. Water, on the other hand, passes through a liquid phase at 1 atmosphere.

Ice nuclei are very rare compared to cloud condensation nuclei on which liquid droplets form. Clays, desert dust, and biological particles can be nuclei. [20] Artificial nuclei include particles of silver iodide and dry ice, and these are used to stimulate precipitation in cloud seeding. [21]
