Solution

The process of Dry ice is Sublimation.

Here are the steps:

  1. Dry ice is the solid form of carbon dioxide (CO2). It's called "dry ice" because it does not melt into a liquid, but instead changes directly from a solid to a gas.

  2. This process is known as sublimation. Sublimation occurs when a substance changes from a solid state to a gas state without ever becoming a liquid.

  3. For sublimation to occur, the substance must be exposed to heat or a decrease in pressure that results in the particles moving more freely and becoming a gas.

  4. In the case of dry ice, it sublimates at temperatures above -78.5 degrees Celsius (-109.3 degrees Fahrenheit).

  5. As dry ice sublimates, it creates a dense, white fog that is often used in theatrical productions or to keep food cold during shipping.

  6. It's important to handle dry ice carefully because it's extremely cold and can cause frostbite or burns if it comes into direct contact with skin.

  7. Also, because it turns into CO
