Correct option is D
Dry ice is the solid form of carbon dioxide (CO2).It is primarily used as a cooling agent due to its ability to sublimate directly from solid to gas without forming a liquid.
Key points:
● Dry ice maintains a temperature of approximately -78.5°C (-109.3°F).
● It is widely used in refrigeration, preservation of perishable goods, and creating fog effects in stage productions.
● Its sublimation property makes it clean and residue-free for cooling purposes.
● Handling dry ice requires precautions like insulated gloves to prevent frostbite.
● It is non-toxic but must be used in well-ventilated spaces to avoid CO2 buildup.
● Dry ice is manufactured by compressing and cooling CO2 gas into its solid state.
Additional Information:
- Washing soda is sodium carbonate (Na2CO3)
- Carbon monoxide is a toxic gas
