What is dry ice? How is it prepared?

Answer 1

Hint: In this type of question we will explain about dry ice with also mentioning about its different properties, as explaining about the preparation part through which we can get our required answer.

Complete answer:

Dry ice is the solid form of carbon dioxide. It is utilized basically as a cooling operator. Its focal points incorporate lower temperature than that of water ice and do not leave any buildup (other than accidental ice from dampness in the environment). It is valuable for safeguarding solidified nourishments where mechanical cooling is inaccessible.
Dry Ice is made by compacting and cooling vaporous $CO_2$ constrained to at first produce fluid $CO_2$.
The fluid is then permitted to extend constrained to deliver $CO_2$ day off, at long last, this snow is compacted by a water driven press into advantageous Dry Ice squares, cuts or pellets. The thickness of the compacted $CO_2$ snow relies upon the applied weight and the weight time. The thickness of the Dry Ice square can arrive at 1.56g/$cm^3$ as a most extreme at a temperature of - 78.64°C

Note: In such a type of question we had a brief knowledge about dry ice and also about its making, as explaining about dry ice and also stating about its making would help us to find the required answer we are looking for.
