Solid CO2 is called dry ice. This is an excellent name because solid CO2 sublimes,
going from liquid to vapor without ever going through the stage of being
a liquid.
Dry ice
Dry ice IS the solid form of carbon dioxide. And "dry ice" IS the common name for the solid CO2. So the question should be "What substance is the common name Dry Ice used for ? "
Dry ice (frozen carbon dioxide)
A good hypothesis for a dry ice bubble experiment could be: "If dry ice is placed in warm water with soap, then bubbles will form due to the release of carbon dioxide gas from the dry ice interacting with the soap molecules."
Dry ice is the solid form of Carbon Dioxide (CO2)
Dry ice is solid carbon dioxide (CO2). It is called dry ice because it does not melt when it heats up, it goes directly from solid to gas. It is NOT the same as ordinary ice, which is of course, solid water. Dry ice is much colder than ordinary ice.
The name of the material is ice.
No, dry ice is not malleable. It is the solid form of carbon dioxide, and it becomes brittle at low temperatures, breaking easily when struck or compressed. Malleability refers to the ability of a material to be shaped or bent without breaking, which does not apply to dry ice.
Because you aren't going to eat frozen ice. Are you? :)
Dry ice is classified as a hazardous material under Class 9 - Miscellaneous hazardous material. Asbestos is classified as a hazardous material under Class 9 - Miscellaneous hazardous material as well.
It is called "dry" because when heat is given, it sublimes (turns from a solid into a gas). This is different from actual ice that turns from a solid to a liquid. It is called "ice" because solid carbon dioxide (dry ice) is very cold, similar to ice.
When ice transforms to water, it is called melting. If it is dry ice, and it evaporates, that is called sublimation.
