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

You are watching: How long to chill a can of soda in the freezer

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

So what happens if you leave soda in the freezer?

There room two possible outcomes if you leave her drink in the freeze: you could have a frozen container that soda if you are very lucky. However in many cases, you’ll have actually an exploded deserve to of soda decorating her icebox.

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

This occurs because of the distinctive chemical nature of water mix explosively v the naturally expansive properties of carbon dioxide gas.

Other liquids can be safely stored in her freezer to end up being chilled and also frozen into a heavy state, however not soda. Both water and also carbon dioxide have actually a propensity to push against their containers under the appropriate circumstances.

Even if the can of soda hasn’t exploded, it’s no a really safe point to handle since putting pressure on the container could trigger the exact same chain reaction defined above.

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

While it’s tempting to usage your freezer come chill a have the right to of soda top top a warm day, there are other methods that can accomplish the very same goal without as lot risk to your icebox or an individual safety.

Expansion of Water In her Soda Can

To totally understand this process, you have to understand exactly how water broadens when the approximately temperature changes with her soda.

Generally, chemistry and also physics dictate that chillier temperatures cause the liquid to contract and warmer temperatures cause the liquid to expand.

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

The reverse is true for cooler temperatures; fluid molecules slow-moving down and thus become much more solid. In fact, once liquids freeze it’s a an outcome of the temperature being so cold that their molecules don’t move roughly as much.

Water adheres to this basic trend, but only up to a certain point. At 4°C, water stops ending up being denser together it cools down and also instead starts to increase as the temperature proceeds to decrease.

This quirk of physics is what renders ice take it up an ext surface area as soon as frozen 보다 the same amount of liquid water, together with some air molecules gift trapped in the latticework the a provided piece the ice.

As girlfriend know, your freezer reaches listed below 4°C. It reaches at the very least 0°C in bespeak to achieve the freezing point of water. This means that any type of fluids had inside her freezer will increase as they with the last stages of transitioning to a solid state that matter.

How This affects Soda Cans and also Bottles

So, just how does this affect soda cans or bottles and also why go it reason an explosion?

Despite every one of the tasty ingredients that comprise a have the right to of Coca-Cola or Pepsi, both beverages and also all other species of soda are mainly water and also carbon dioxide. In fact, water is the solitary ingredient that renders up the bulk of the matter in a offered can of soda.

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

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

You see, as the water expands, it likewise puts pressure on the carbon dioxide gas to escape the confinement. Unlike constant water, carbon dioxide is relatively explosive if friend unleash it easily through a tiny opening.

Imagine opening a can of soda; the prompt hiss girlfriend hear is the carbon dioxide escaping with the height rapidly. When a have the right to of soda explodes, it’s due to the fact that the water and CO2 have actually put so lot pressure on the can that the framework can’t resist it any type of longer.

The aluminum have the right to of a normal soda is solid enough to withstand normal push changes and hold the carbonation pressure from the carbon dioxide gas.

But it’s not developed to take care of the type of pressure the comes with whole can of fluid trying come expand. Together you might imagine, the widening water has nowhere to go, increasing the stress and anxiety on the aluminum can, specifically its weaker points like the tab i m sorry you usage for opening the soda to drink.

These weak points only become an ext stressed together the water and CO2 proceed to expand and also reach 0°C. This is not a suddenly process; that’s why some cans of soda will certainly actually make it all the means to the freezing allude and come to be frozen solid without exploding.

In those cases, the expansion impact that happens slowly sufficient in the aluminum deserve to was solid enough to withstand the change.

But in most cases, the slight press buildup will eventually reach a breaking suggest and cause the peak of the soda can to accurate blast off.

In some circumstances, the center of the deserve to may be the weakest point, therefore this is the clues that will explode outward, sending out shards that ice and aluminum everywhere. It’s rather a mess.

It’s simple physics; the water and gas inside the can expand and the aluminum have the right to isn’t strong enough to store it contained. Therefore, using a freezer come cool down a deserve to of soda is a risky venture.

Note that this entire procedure is no much longer relevant if the deserve to of soda is currently opened. It’s perfectly fine to put a cup the uncovered soda right into the freezer since there will certainly be enough room for the expanding liquid to occupy without putting a strain on the container.

Can friend Still use the Freezer to Cool Soda?

As pointed out above, you can constantly use the freezer to cool soda if it’s in an additional container besides the original sealed have the right to or bottle.

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

You have to pay very close attention once using the freezer to supply a rapid burst the cold before drinking to avoid dropping the temperature as well much.

The idea is to take the soda out before it reaches 4°C when the water within the deserve to would begin to expand.

Taking the can out before this suggest will enable you to enjoy cooler soda there is no risking the explosive effect.

Ideally, you’d want to store a near eye ~ above the soda and check it after about 20 minutes. Anything after 20 minutes or so risks the can drop come a temperature below 4°C, which could put press on the can.

In this case, you have to be careful when taking care of the can or party of soda as disturbing the container could reason a preemptive explosion.

Alternative methods To Cool her Soda

Instead of risking an exploding have the right to of soda, over there are better ways to present your soft drink, and also much much more rapidly, to boot.

You could always place a can of soda in the refrigerator. The ambient cool temperature inside will certainly slowly adjust the temperature of your soda, although air is a bad heat conductor and will only accomplish this process slowly.

By far, the best means to cool under your can of soda is to put it in a cooler or bath of ice water.

Another amazing property the water is its warmth retention. A warm have the right to of soda placed into ice cream water will conveniently transfer that warm into the water itself, leave the can ice cold much much more quickly 보다 if girlfriend left the soda in your refrigerator.

Water sucks away heat a lot much more efficiently than regular air.

This is partly due to water’s own chemical properties and the fact that water is a much denser collection of molecules 보다 ambient air. Every one of that water have the right to run over the surface ar of your deserve to of soda, touching an ext of the have the right to than wait does in less time.

The much more surface area got to by the ice cream water, the quicker the cooling procedure takes place. Because water retains heat an extremely well, over there won’t be lot of a feedback loop, therefore your have the right to will continue to be cold rather than suck up heat that the water bring away on from the environment.

Overall, using an ice bath to cool under a deserve to of soda must only take a couple of minutes together opposed to the hours compelled by a modern-day refrigerator, and also all there is no the danger of an explosive mess the comes through using a freezer.
