Yes, it is possible: the phenomenon is called sublimation.
Dry ice is solid carbon dioxide. Carbon dioxide goes from a solid phase to a gaseous phase without becoming a liquid and that transition is called sublimation.
Sublimation is the process in which a solid turns directly into a gas without passing through the liquid phase. Dry ice (solid carbon dioxide) is an example of a substance that undergoes sublimation when it is exposed to normal atmospheric conditions.
Gas. Like Oxygen, Carbon Dioxide and Helium etc.
The phase change from a solid to a gas is called sublimation. This process occurs when a substance goes directly from a solid state to a gaseous state without passing through the liquid state. Examples include dry ice (solid carbon dioxide) sublimating into carbon dioxide gas at room temperature.
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Carbonic acid is H2CO3 (carbon dioxide dissolved in water) and is known in liquid and gaseous phase.
Nope. The pressure keeps the Carbon Dioxide dissolved in the liquid, and when that pressure is relieved, the CO2 rapidly returns to its gaseous state. None of the molecules are reacting or changing, although the CO2 switches from aqueous to gaseous phase.
At -60 degrees Celsius and standard atmospheric pressure (1 ATM), carbon dioxide exists in a solid phase, commonly referred to as dry ice. This temperature is below the sublimation point of carbon dioxide, where it transitions directly from solid to gas without becoming a liquid. Therefore, at these conditions, carbon dioxide would not be found in its gaseous or liquid form.
When carbon dioxide snow (or dry ice) disappears, it undergoes sublimation, a physical change in which a solid transforms directly into a gas without passing through the liquid phase. As the dry ice warms, it absorbs heat energy from the surrounding environment, causing the solid carbon dioxide to convert into carbon dioxide gas. This process results in the visible disappearance of the dry ice as it transitions from a solid to a gaseous state.
no. a phase change is ALWAYS a physical change in the substance.
The bubbling of recently opened pressurized containers of soda water is not considered a chemical reaction; it is simply the change of some carbon dioxide from solution in water to a gaseous phase.
No, dry ice pieces do not become smaller through condensation. Rather they become smaller through sublimation, the physical change of matter from a solid phase to a gaseous phase. Condensation is the physical change of matter from a gaseous phase to a liquid phase, such as when you blow on your eyeglasses to fog them up so you can wipe them clean. Since dry ice is solid carbon dioxide, it cannot undergo condensation.
