Dry ice is widely used for transporting perishable items such as food, pharmaceuticals, and biological samples that require a consistently low temperature. Its sublimation process (direct transition from solid to gas) at low temperatures makes it ideal for maintaining a cold environment without the use of traditional refrigerants. dry ice is valued for its ability to provide intense cooling without leaving liquid residue, making it versatile across industries that require controlled low-temperature environments or specific physical properties like its sublimation characteristics.
