How solid carbon dioxide is formed?

Question

Answer

Dry ice is the solid form of carbon dioxide (CO2), a molecule consisting of a singlecarbon atom bonded to two oxygen atoms. Dry ice is colorless, non-flammable, with a sour zesty odor, and can lower the pH of a solution when dissolved in water, forming carbonic acid (H2CO3).

Answer

Solid carbon dioxide is called dry ice. It is called because when it is exposed to air , the pressure acting on it falls to about 1 atmosphere .As a result , it sublimes ,i.e., directly gets converted into gaseous carbon dioxide without passing through the intervening liquid state . Consequently , unlike ordinary ice , it does wet the surface on which it is kept . That is why it is called dry ice . It is prepared by cooling carbon dioxide under pressure.

Answer

Solid carbon dioxide, commonly known as dry ice, is formed through a process called sublimation. This occurs when carbon dioxide gas is cooled and compressed into a solid state without passing through the liquid phase. The process involves several steps, which are explained below.

Cooling and compressing the gas
The first step in forming solid carbon dioxide is to cool and compress the gas to high pressures. This is typically done using a refrigeration system or a dry ice maker. As the gas is compressed, it begins to liquefy and then solidify as the temperature drops below -109.3°F (-78.5°C).

Molding and shaping
Once the solid carbon dioxide is formed, it can be molded and shaped into a variety of forms, such as blocks, pellets, or slices. This is done using specialized equipment that applies pressure and heat to the solid carbon dioxide.

Packaging and transportation
After the solid carbon dioxide has been molded and shaped, it is packaged and transported to its final destination. This is typically done in insulated containers that keep the dry ice cold and prevent it from sublimating too quickly.

Uses of solid carbon dioxide
Solid carbon dioxide is commonly used in a variety of applications, including:

- As a refrigerant in transportation and storage of food and other perishable products
- In the pharmaceutical industry for the transport and storage of temperature-sensitive products
- In the entertainment industry for special effects, such as creating fog and smoke
- In research and development for the preservation of biological samples and tissues.

In conclusion, solid carbon dioxide is formed through a process called sublimation, which involves cooling and compressing carbon dioxide gas to high pressures and temperatures. The resulting solid can be molded and shaped into various forms and is commonly used in a variety of industries for its unique properties.

Answer

On lowering down the temperature of Co2, it cools down and gets converted into solid form that is known as dry ice.

Answer

By lowering the temperature of Co2 , it cools down and converted into solid state
