What is the process of Dry ice?SublimationCondensationSolidificationFusion
Solution
The process of Dry ice is Sublimation.
Here are the steps:
-
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.
-
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.
-
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.
-
In the case of dry ice, it sublimates at temperatures above -78.5 degrees Celsius (-109.3 degrees Fahrenheit).
-
As dry ice sublimates, it creates a dense, white fog that is often used in theatrical productions or to keep food cold during shipping.
-
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.
-
Also, because it turns into CO
