This article delves into the world of dry ice, its properties, and whether it’s a viable option for keeping your fridge cold.
Understanding Dry Ice
Dry ice is the solid form of carbon dioxide (CO2), which is a natural byproduct of various industrial processes. It’s called “dry” because it doesn’t contain water, unlike regular ice, which is made from frozen water. Dry ice changes directly from a solid to a gas at room temperature, a process known as sublimation. This unique property makes dry ice extremely cold, with a temperature of -109°F (-78.5°C), which is colder than the freezing point of water (32°F or 0°C).
