On a warm summer day, there’s regularly nothing much better than ice-cold soda pop. Yet if you forgot to litter your recent batch in the fridge and need come cool it under in a hurry, girlfriend might consider putting a deserve to of soda in your freezer.

You are watching: How long can you leave a can of soda in the freezer

After all, your freezer is chillier than her refrigerator, and also cooling that this way way you don’t need to water the soda down v a chunk of ice.

So what happens if you leaving soda in the freezer?

There space two feasible outcomes if you leave your drink in the freeze: you can have a frozen container that soda if you are an extremely lucky. Yet in numerous cases, you’ll have actually an exploded deserve to of soda decorating her icebox.

A have the right to of soda that has just exploded will certainly sound a according to “pop” and leave the internal of the icebox coated in snowy soda remnants, together with shards that the aluminum can or plastic bottle.

This occurs due to the unique chemical nature of water mix explosively v the naturally expansive properties of carbon dioxide gas.

Other liquids have the right to be safely save on computer in your freezer to end up being chilled and frozen into a solid state, yet not soda. Both water and also carbon dioxide have actually a tendency to push versus their containers under the best circumstances.

Even if the deserve to of soda hasn’t exploded, it’s not a very safe point to handle because putting push on the container could create the very same chain reaction described above.

Overall, putting soda in the freezer isn’t a clever idea even if you’re desperate for a cool drink.

While it’s tempting to usage your freezer come chill a deserve to of soda on a warm day, there space other approaches that can attain the very same goal there is no as much risk to her icebox or personal safety.

Expansion that Water In her Soda Can

To totally understand this process, you have to understand exactly how water expands when the approximately temperature alters with your soda.

Generally, chemistry and also physics dictate that colder temperatures reason the liquid to contract and warmer temperatures reason the fluid to expand.

This is because greater temperatures reason liquids come become much more gaseous together a result of an ext energy in the environment surrounding the liquid.

The reverse is true for chillier temperatures; fluid molecules sluggish down and also thus become much more solid. In fact, when liquids freeze it’s a an outcome of the temperature being so cold the their molecule don’t move approximately as much.

Water complies with this general trend, yet only as much as a specific point. In ~ 4°C, water stops coming to be denser as it cools down and also instead beginning to broaden as the temperature continues to decrease.

This quirk of physics is what makes ice take up more surface area as soon as frozen 보다 the very same amount of fluid water, in addition to some waiting molecules being trapped in the latticework of a given piece that ice.

As friend know, her freezer reaches listed below 4°C. The reaches at the very least 0°C in stimulate to attain the freezing suggest of water. This means that any kind of fluids consisted of inside her freezer will broaden as they reach the final stages of transitioning to a solid state the matter.

How This affect Soda Cans and also Bottles

So, just how does this impact soda cans or bottles and why does it cause an explosion?

Despite every one of the tasty ingredients that make up a can of Coca-Cola or Pepsi, both beverages and also all other varieties of soda are mainly water and also carbon dioxide. In fact, water is the single ingredient that makes up the bulk of the issue in a provided can of soda.

This way that every have the right to of soda is usually a ticking time bomb if you stick it right into your freezer. That’s 16 or for this reason ounces the liquid will chill until it reaches 4°C, then begin to expand.

However, water alone would not cause an explosive effect. The visibility of carbon dioxide is the an enig ingredient.

You see, as the water expands, it also puts pressure on the carbon dioxide gas come escape that confinement. Unlike continual water, carbon dioxide is reasonably explosive if you unleash it conveniently through a little opening.

Imagine opened a have the right to of soda; the immediate hiss friend hear is the carbon dioxide escaping v the peak rapidly. Once a have the right to of soda explodes, it’s because the water and CO2 have put so much pressure on the have the right to that the framework can’t stand up to it any type of longer.

The aluminum can of a common soda is strong enough to resist normal press changes and hold the carbonation push from the carbon dioxide gas.

But it’s not constructed to handle the type of pressure that comes with an entire can of liquid trying come expand. Together you can imagine, the broadening water has actually nowhere to go, enhancing the anxiety on the aluminum can, specifically its weaker points choose the tab which you usage for opened the soda come drink.

These weak points only become more stressed as the water and also CO2 continue to expand and reach 0°C. This is no a sudden process; that’s why part cans of soda will actually do it every the method to the freezing allude and end up being frozen solid there is no exploding.

In those cases, the expansion result that wake up slowly enough in the aluminum deserve to was solid enough to stand up to the change.

But in many cases, the slight push buildup will eventually reach a breaking allude and cause the top of the soda have the right to to literally blast off.

In part circumstances, the middle of the deserve to may be the weakest point, therefore this is the spot that will explode outward, sending shards of ice and aluminum everywhere. It’s quite a mess.

It’s basic physics; the water and gas inside the deserve to expand and also the aluminum can isn’t solid enough to save it contained. Therefore, using a freezer to cool under a can of soda is a risky venture.

Note that this entire process is no much longer relevant if the deserve to of soda is currently opened. It’s perfectly fine to placed a cup the uncovered soda right into the freezer since there will be enough room for the broadening liquid to accounting without placing a strain on the container.

Can friend Still use the Freezer come Cool Soda?

As discussed above, girlfriend can constantly use the freezer to cool soda if it’s in another container besides the original sealed can or bottle.

Of course, a cup filled come the brim with soda will certainly overflow as the fluid expands, but it won’t explode and also cause as much of a mess within the freezer.

You have to pay very close attention when using the freezer to deliver a quick burst of cold before drinking to avoid dropping the temperature too much.

The idea is to take the soda out prior to it will 4°C once the water inside the can would start to expand.

Taking the have the right to out prior to this allude will allow you to enjoy cooler soda there is no risking the explosive effect.

Ideally, you’d want to store a near eye on the soda and also check that after around 20 minutes. Anything after 20 minutes or so risks the have the right to drop to a temperature listed below 4°C, which could put pressure on the can.

In this case, you need to be cautious when dealing with the have the right to or bottle of soda together disturbing the container could cause a preemptive explosion.

Alternative techniques To Cool your Soda

Instead of risking an exploding deserve to of soda, there are much better ways to show your soft drink, and much more rapidly, come boot.

You could constantly place a can of soda in the refrigerator. The ambient cool temperature inside will slowly adjust the temperature of her soda, although waiting is a poor heat conductor and also will only accomplish this procedure slowly.

By far, the best method to cool down your can of soda is to placed it in a cooler or bath of ice water.

Another exciting property the water is its heat retention. A warm deserve to of soda inserted into ice cream water will conveniently transfer that warm into the water itself, leaving the can ice cold much an ext quickly 보다 if you left the soda in your refrigerator.

Water sucks away warmth a lot much more efficiently than continual air.

This is partly as result of water’s very own chemical properties and also the truth that water is a much denser collection of molecules than ambient air. All of that water deserve to run end the surface of your have the right to of soda, touching more of the have the right to than air does in less time.

The an ext surface area reached by the ice water, the much faster the cooling process takes place. Because water maintain heat really well, over there won’t be much of a feedback loop, therefore your can will stay cold rather than sucking up heat that the water bring away on from the environment.

Overall, utilizing an ice cream bath come cool down a can of soda need to only take it a couple of minutes together opposed to the hours compelled by a contemporary refrigerator, and also all without the hazard of an explosive mess the comes through using a freezer.
