Dry ice is a fascinating substance that many people are curious about. It is the solid form of carbon dioxide, a gas that we exhale and plants absorb. Dry ice gets its name because it doesn’t melt like regular ice, but instead transforms directly from a solid to a gas in a process called sublimation.
But what happens when you put dry ice in the freezer? Does it melt or undergo sublimation as it normally does? These are questions that frequently arise, and today we will find the answers.
The short answer is that dry ice does not melt in the freezer. While regular ice melts when exposed to the temperature of the freezer, dry ice remains solid. This is because the extremely low temperature of the freezer keeps the dry ice below its sublimation point, which is around -78.5 degrees Celsius (-109.3 degrees Fahrenheit).
What is Dry Ice
Dry ice is the solid form of carbon dioxide. It is called dry ice because it does not melt into a liquid when it is heated; instead, it undergoes a process called sublimation, where it changes directly from a solid to a gas. This unique property makes dry ice useful for a variety of applications.
Dry ice is extremely cold, with a temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit). It is so cold that it can cause frostbite if it comes into contact with bare skin. Therefore, it is important to handle dry ice with care and use proper protective equipment, such as gloves and goggles, when working with it.
One of the most common uses of dry ice is as a cooling agent. Due to its extremely low temperature, dry ice can be used to keep things frozen without the need for traditional ice or a refrigeration unit. It is often used in transportation and shipping to keep perishable items, such as food or medical supplies, frozen during transit.
Another use of dry ice is in the entertainment industry. It is often used to create special effects, such as producing smoke or fog. When dry ice is added to warm water, it sublimates and creates a dense, cloud-like vapor that can be used to create an eerie or dramatic effect on stage or in movies.
In addition, dry ice can be used for cleaning. Its sublimation process creates pressure that can be used to blast away dirt, grime, and contaminants from various surfaces. This makes dry ice blasting a popular method for cleaning sensitive electronic equipment or removing stubborn residue.
Overall, dry ice is a versatile substance with unique properties that make it useful in various industries. Its ability to remain solid at low temperatures and sublimate instead of melt makes it a valuable tool for cooling, special effects, and cleaning applications.

How Does Dry Ice React in the Freezer
Dry ice, which is the solid form of carbon dioxide, reacts differently in the freezer compared to traditional ice. This unique substance undergoes a process known as sublimation, wherein it transitions directly from a solid state to a gas without turning into a liquid.
When placed in the freezer, dry ice continues to sublimate, albeit at a slower rate compared to when it is exposed to room temperature. The extremely cold temperatures of the freezer cause the dry ice to sublimate at a slower pace, resulting in a longer-lasting effect.
One interesting phenomenon that occurs when using dry ice in the freezer is the formation of a layer of frost on its surface. As the dry ice sublimates, the carbon dioxide gas mixes with the cold air in the freezer and creates a frosty covering on the dry ice. This frost acts as an insulating layer, slowing down the sublimation process even further.
It is important to handle dry ice with care in the freezer as well. Due to its extremely low temperature (-78.5 degrees Celsius or -109.3 degrees Fahrenheit), direct contact with skin can cause frostbite or burns. Always use thick gloves or tongs when handling dry ice, even when it is inside the freezer.
Using dry ice in the freezer can have several practical applications. It can be utilized to maintain extremely low temperatures, such as when storing and transporting sensitive items like vaccines, frozen food, or perishable goods. Additionally, it can be used for special effects in food presentation or theatrical productions, providing a visually appealing display of smoke or fog.
- Dry ice in the freezer sublimates from a solid to a gas
- The extremely cold temperatures in the freezer slow down the sublimation process
- A layer of frost forms on the surface of the dry ice, further insulating it
- Handle dry ice with caution in the freezer due to its low temperature
- Dry ice in the freezer has practical uses such as preserving sensitive items and creating special effects
Is It Safe to Put Dry Ice in the Freezer
Putting dry ice in the freezer can be dangerous and should be avoided.
Dry ice is primarily composed of solid carbon dioxide and is much colder than regular ice. Placing dry ice in the freezer can cause the temperature to drop rapidly, potentially creating a hazardous environment.
Here are a few reasons why it is not safe to put dry ice in the freezer:
- Risk of explosion: Dry ice undergoes a process called sublimation, where it converts directly from a solid to a gas. If stored in a closed container, the pressure from the gas buildup can cause an explosion.
- Temperature imbalance: Dry ice has an extreme cold temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit). Placing it in the freezer can disrupt the balance and temperature control of the freezer, leading to potential damage or malfunction.
- Health hazards: Dry ice releases carbon dioxide gas as it sublimates. If there is insufficient ventilation in the freezer, the build-up of carbon dioxide can displace oxygen and pose a risk of asphyxiation.
Instead of putting dry ice in the freezer, here are some recommendations for handling dry ice:
- Use adequate ventilation: When storing or transporting dry ice, always ensure sufficient airflow to prevent the buildup of carbon dioxide gas.
- Wear protective gloves: Direct contact with dry ice can cause frostbite or skin injuries. Use insulated gloves or tongs when handling dry ice to avoid any personal injury.
- Store in a well-ventilated container: Dry ice should be stored in a container that allows for the release of carbon dioxide gas. Avoid sealing it in airtight containers to prevent pressure buildup.
- Dispose of properly: When no longer needed, allow the dry ice to sublimate in a well-ventilated area. Do not dispose of dry ice in a regular trash bin or confined space.
By following these guidelines, you can ensure the safe handling and use of dry ice without jeopardizing your freezer or your well-being.
FAQ
Can dry ice melt in the freezer?
No, dry ice does not melt in the freezer. It undergoes a process called sublimation, where it changes directly from a solid to a gas without passing through a liquid phase.
Why doesn’t dry ice melt in the freezer?
Dry ice doesn’t melt in the freezer because it has a temperature of -78.5 degrees Celsius (-109.3 degrees Fahrenheit). At this temperature, it is colder than the freezing point of water, so it doesn’t turn into a liquid.
Is it safe to put dry ice in the freezer?
Yes, it is safe to put dry ice in the freezer. However, you should handle dry ice with caution and follow proper safety guidelines. Make sure to keep the area well-ventilated and avoid sealing the dry ice in an airtight container to prevent pressure build-up.
