Getting to Know Dry Ice
Dry ice is a pretty cool substance (pun intended) with some nifty uses, especially when it comes to keeping things cold. But will it stay frozen in your freezer? Let's break it down.
What Exactly is Dry Ice?
Dry ice is just frozen carbon dioxide (CO₂). Unlike the ice cubes in your drink, which are made from water, dry ice forms when CO₂ is chilled to a bone-chilling -109.3°F (-78.5°C). This super cold temperature turns the gas into a solid. And here's the kicker: dry ice doesn't melt into a puddle. Instead, it goes straight from solid to gas in a process called sublimation.
| Property | Value |
|---|---|
| Chemical Formula | CO₂ |
| Freezing Point | -109.3°F (-78.5°C) |
| Sublimation Point | -78.5°C |
Dry ice is a go-to for keeping stuff fresh, creating spooky fog effects, and even in some science experiments.
What Makes Dry Ice Special?
Dry ice has some standout features that set it apart from your everyday ice. These are key to understanding how it works and how to store it.
Super Cold: Dry ice is seriously cold at -109.3°F (-78.5°C). It's great for freezing and preserving things that need to stay really cold.
Sublimation: Instead of melting, dry ice sublimates. It skips the liquid phase and goes straight from solid to gas, which means no messy puddles.
Heavy Duty: Dry ice is denser than regular ice, so it lasts longer and cools more effectively.
Safe to Use: Dry ice won't catch fire, so it's safe for a variety of uses without worrying about it igniting.
These features make dry ice a top pick for cooling needs. But, because it's so cold and turns into gas, you need to handle and store it carefully.

Storing Dry Ice: Keep It Cool and Safe
Keeping dry ice in good shape isn't just about making it last longer—it's about staying safe too. Let's break down how to handle and store dry ice the right way, and how long you can expect it to stick around.
Handling and Storing Dry Ice
Dry ice is super cold—like, "ouch, that burns!" cold. So, you gotta be careful. Here’s how to handle it without turning your fingers into popsicles:
- Gloves and Tongs: Always use insulated gloves or tongs. Trust me, your skin will thank you.
- Insulated Container: A cooler works great. It slows down the melting (or sublimation, if you wanna get fancy).
- Ventilation is Key: Make sure the container isn't airtight. Otherwise, you might end up with a mini explosion from the gas build-up.
- Well-Ventilated Area: Store it somewhere with good airflow to avoid a carbon dioxide gas party in your house.
How Long Does Dry Ice Last?
How long dry ice lasts depends on how you store it and how much you have. On average, it disappears at about 5-10 pounds every day in a regular cooler. Here’s a quick look at how long different amounts will last:
| Amount of Dry Ice | Duration (Hours) |
|---|---|
| 5 pounds | 12-24 |
| 10 pounds | 24-48 |
| 20 pounds | 48-72 |
| 50 pounds | 72-120 |

Freezing Point of Dry Ice
Temperature of Dry Ice
Dry ice, the solid form of carbon dioxide, is way colder than your regular ice. We're talking -109.3°F (-78.5°C). This super low temperature means it skips the whole melting thing and goes straight from solid to gas. Handy for keeping stuff cold, but you gotta handle it with care.
| Substance | Temperature (°F) | Temperature (°C) |
|---|---|---|
| Dry Ice | -109.3 | -78.5 |
| Regular Ice | 32 | 0 |
How Dry Ice Acts in Different Spots
Dry ice is a bit of a drama queen when it comes to temperature changes. If it gets warmer than -109.3°F (-78.5°C), it starts turning into gas. So, in your average home freezer (around 0°F or -18°C), dry ice won't stay solid for long.
| Environment | Temperature (°F) | Temperature (°C) | Dry Ice State |
|---|---|---|---|
| Household Freezer | 0 | -18 | Turns to Gas |
| Room Temperature | 68 - 72 | 20 - 22 | Turns to Gas |
| Specialized Freezer | -109.3 | -78.5 | Stays Solid |
Knowing how dry ice behaves in different places is key to using it right. Stick it in a regular freezer, and it'll just vanish into thin air. Want more details? Check out our article on will dry ice keep in the freezer?.

Dry Ice in Freezer
Ever wondered if you can stash dry ice in your freezer? Let's break it down and see if it’s a good idea or a recipe for disaster.
Can You Put Dry Ice in a Freezer?
Putting dry ice in a freezer might sound like a no-brainer to keep it solid longer. But hold up! Dry ice is a different beast. It's basically frozen carbon dioxide (CO2) and needs super chilly temps to stay solid.
Your average household freezer chills at about 0°F (-18°C). But dry ice? It needs to be at -109.3°F (-78.5°C) to stay solid. So, if you toss dry ice into your regular freezer, it’s gonna turn into gas pretty fast because your freezer just isn’t cold enough.
Will Dry Ice Stay Frozen in a Freezer?
So, will dry ice stay frozen in your freezer? Nope. The freezer’s just not cold enough. Instead of staying solid, the dry ice will sublimate, which is a fancy way of saying it’ll go from solid to gas without turning into a liquid first.
| Condition | Temperature | Dry Ice State |
|---|---|---|
| Sublimation Point | -109.3°F (-78.5°C) | Solid |
| Typical Freezer | 0°F (-18°C) | Gas |

Safety Concerns
Storing dry ice in a freezer isn’t just ineffective—it can be risky. As it sublimates, CO2 gas builds up inside the freezer. This can create pressure that might damage your freezer or even pose safety hazards. For safe handling and storage tips, see our guide on proper handling and storage of dry ice.
Alternatives for Keeping Things Cold

So, next time you think about putting dry ice in your freezer, remember: it’s a no-go. Stick to regular ice and keep things cool the safe way!
Safety Precautions
Handling dry ice isn't rocket science, but it does need some care. Let's break down how to keep things safe and sound when you're dealing with this frosty stuff.
Handling Dry Ice Safely
Dry ice is just solid carbon dioxide, but it can give you a nasty burn if you touch it with your bare hands. So, gear up! Here’s how to handle it without turning into a popsicle:
- Gloves Are Your Best Friend: Thick, insulated gloves are a must. Think of them as your dry ice armor.
- Tools, Not Hands: Use tongs or scoops to move dry ice around. Your hands will thank you.
- Fresh Air, Always: Dry ice turns into carbon dioxide gas, which can be dangerous in tight spaces. Make sure you’re in a well-ventilated area.
- Keep It Cool: Store dry ice in an insulated container to slow down how fast it turns back into gas.
Risks and Precautions to Take
Knowing the risks can save you a lot of trouble. Here’s what you need to watch out for and how to stay safe:
- Burns: Touching dry ice can give you frostbite. Always wear those thick gloves.
- Breathing Trouble: In small spaces, the gas from dry ice can push out the oxygen. Keep the area well-ventilated.
- Boom!: Sealing dry ice in a container can make it explode. Use containers that let the gas escape.
| Risk | Safety Measure |
|---|---|
| Frostbite | Wear thick, insulated gloves |
| Asphyxiation | Ensure good ventilation |
| Explosion | Use vented containers |

Getting Rid of Dry Ice
Safe Ways to Dispose of Dry Ice
Dry ice can be tricky to handle because it's super cold and turns straight into gas. Here’s how to get rid of it safely:
- Let It Turn to Gas in Open Air: The best way to dispose of dry ice is to let it turn into gas (sublimate) in a place with good airflow, like outside. This stops carbon dioxide gas from building up.
- Avoid Closed Spaces: Never put dry ice in places like trash cans, sinks, or toilets. The gas can build up pressure or push out oxygen, which can be dangerous.
Safety Tips for Handling Dry Ice
When getting rid of dry ice, you need to be careful to keep yourself and others safe. Here are some important tips:
- Wear Gloves: Always use insulated gloves when touching dry ice. It’s so cold it can give you frostbite.
- Ventilate the Area: Make sure there’s good airflow where you’re letting the dry ice turn to gas. Carbon dioxide can build up and make it hard to breathe.
- Keep It Away from Kids and Pets: Don’t let kids or pets near dry ice. It’s too cold and can be dangerous if not handled right.
- Don’t Use Sealed Containers: Never put dry ice in sealed containers. The gas can build up and make the container explode.
