The solid form of carbon dioxide is known as dry ice. Unlike regular ice made from water, dry ice sublimates, transitioning directly from solid to gas without becoming liquid. This unique property makes dry ice particularly useful in various applications, including food preservation, creating fog effects in theatrical productions, and as a coolant for shipping perishable items. However, safety precautions are necessary when handling dry ice, as its extremely low temperature can cause skin burns, and the gas produced during sublimation can displace oxygen in enclosed spaces.
