Dry ice is the solid form of carbon dioxide. It is a white, powdery substance that is very cold, with a temperature of -109.3 degrees Fahrenheit (-78.5 degrees Celsius). Dry ice is used in a variety of applications, including food preservation, shipping perishable goods, and creating special effects. However, dry ice can be dangerous if it is not handled properly. It can cause frostbite if it comes into contact with skin, and it can release carbon dioxide gas, which can be harmful if inhaled.
It is important to dispose of dry ice properly to avoid these hazards. Dry ice should never be disposed of in the trash, as it can cause the trash can to explode. It should also never be disposed of in the sink or toilet, as it can clog the drains. The best way to dispose of dry ice is to allow it to sublimate, which means to change from a solid directly to a gas. This can be done by placing the dry ice in a well-ventilated area and allowing it to sit until it has completely disappeared.
