Dry ice is the solid form of carbon dioxide (CO 2), a molecule consisting of a single carbon atom bonded to two oxygen atoms. Dry ice is colorless, odorless, and non-flammable, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H 2 CO 3). [1]

The confusion was compounded when Paul Thénard wrote a biography of his father, Louis Thénard, a French chemist: [3] In 1835, Adrien Thilorier had created dry ice by spraying liquid carbon dioxide into a glass vessel. He had thought that the dry ice was merely snow; that is, water vapor from the atmosphere which had condensed as a result of ...
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 ...
Underwater explosions using dry ice and liquid nitrogen are captured in high definition slow motion by The Backyard Scientist.
Start End c. 5600 BC According to the Black Sea deluge theory, the Black Sea floods with salt water. Some 3000 cubic miles (12,500 km 3) of salt water is added, significantly expanding it and transforming it from a fresh-water landlocked lake into a salt water sea. c. 5500 BC
With radiation equilibrium temperatures of 40–50 K, [177] the objects in the Kuiper Belt are expected to have amorphous water ice. While water ice has been observed on several objects, [178] [179] the extreme faintness of these objects makes it difficult to determine the structure of the ices. The signatures of crystalline water ice was ...
There were no more near-seedings until 1969. In the interim, equipment was improved. What once was the primitive method of hand-dumping dry ice was replaced with rocket canisters loaded with silver iodide, and then gun-like devices mounted on the wings of the airplanes that fired silver iodide into the clouds. Observation equipment was improved ...
