On a hot summer day, there’s regularly nothing far better than ice-cold soda pop. However if you forgot to throw your recent batch in the fridge and need to cool it under in a hurry, you might think about putting a have the right to of soda in her freezer.

You are watching: How long does it take for a soda to explode in the freezer

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

So what wake up if you leaving soda in the freezer?

There space two possible outcomes if friend leave her drink in the freeze: you can have a frozen container that soda if girlfriend are really lucky. However in plenty of cases, you’ll have an exploded have the right to of soda decorating your icebox.

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

This occurs as result of the distinct chemical properties of water mixing explosively with the naturally expansive properties of carbon dioxide gas.

Other liquids have the right to be safely save in her freezer to end up being chilled and frozen right into a hard state, but not soda. Both water and also carbon dioxide have actually a tendency to push versus their containers under the ideal circumstances.

Even if the deserve to of soda hasn’t exploded, it’s no a really safe thing to handle due to the fact that putting push on the container could cause the very same chain reaction defined above.

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

While it’s tempting to use your freezer to chill a can of soda top top a warm day, there are other methods that can achieve the same goal there is no as much risk to your icebox or personal safety.

Expansion of Water In her Soda Can

To fully understand this process, you have to understand how water increases when the approximately temperature changes with her soda.

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

This is because higher temperatures cause liquids to become an ext gaseous together a result of much more energy in the environment surrounding the liquid.

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

Water complies with this general trend, however only up to a specific point. At 4°C, water stops becoming denser together it cools down and instead starts to broaden as the temperature proceeds to decrease.

This quirk of physics is what provides ice take it up more surface area when frozen 보다 the exact same amount of fluid water, together with some waiting molecules being trapped in the latticework of a provided piece that ice.

As friend know, your freezer reaches listed below 4°C. It reaches at least 0°C in bespeak to attain the freezing point of water. This method that any type of fluids had inside her freezer will increase as they reach the final stages the transitioning to a solid state of matter.

How This influence Soda Cans and Bottles

So, just how does this affect soda cans or bottles and also why does it reason 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 primarily water and also carbon dioxide. In fact, water is the solitary ingredient that provides up the bulk of the issue in a provided can the soda.

This means that every deserve to of soda is basically a ticking time bomb if you stick it into your freezer. That’s 16 or so ounces of liquid will chill until it will 4°C, then begin to expand.

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

You see, together the water expands, it also puts pressure on the carbon dioxide gas come escape that confinement. Unlike continuous water, carbon dioxide is relatively explosive if girlfriend unleash it quickly through a little opening.

Imagine opening a deserve to of soda; the immediate hiss you hear is the carbon dioxide escaping with the height rapidly. When a have the right to of soda explodes, it’s because the water and also CO2 have put so much pressure ~ above the deserve to that the framework can’t withstand it any type of longer.

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

But it’s not developed to manage the type of pressure the comes with whole can of liquid trying to expand. Together you might imagine, the expanding water has nowhere to go, increasing the tension on the aluminum can, particularly its weaker points favor the tab i m sorry you usage for opening the soda come drink.

These weak points just become much more stressed as the water and also CO2 continue to expand and reach 0°C. This is not a sudden process; that’s why part cans of soda will actually do it all the way to the freezing point and end up being frozen solid without exploding.

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

But in most cases, the slight press buildup will at some point reach a breaking point and reason the top of the soda have the right to to literally blast off.

In part circumstances, the center of the can may it is in the weakest point, for this reason this is the clues that will certainly explode outward, sending shards the ice and also aluminum everywhere. It’s fairly a mess.

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

Note the this entire procedure is no longer relevant if the have the right to of soda is already opened. It’s perfect fine to placed a cup of uncovered soda right into the freezer since there will be enough space for the widening liquid to occupy without placing a strain on the container.

Can friend Still usage the Freezer come Cool Soda?

As stated above, you can always use the freezer to cool soda if it’s in an additional container besides the original sealed deserve to or bottle.

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

You need to pay an extremely close attention as soon as using the freezer to provide a fast burst that cold prior to drinking to protect against dropping the temperature also much.

The idea is to take the soda out before it get 4°C when the water within the have the right to would start to expand.

Taking the can out before this allude will enable you to enjoy cooler soda without risking the explosive effect.

Ideally, you’d desire to keep a nearby eye ~ above the soda and also check the after about 20 minutes. Anything after ~ 20 minute or so risks the can drop to a temperature below 4°C, which can put pressure on the can.

In this case, you need to be cautious when handling the deserve to or bottle of soda as disturbing the container could reason a preemptive explosion.

Alternative methods To Cool her Soda

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

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

By far, the best method to cool under your deserve to of soda is to placed it in a cooler or bathtub of ice cream water.

Another amazing property the water is its warmth retention. A warm deserve to of soda placed into ice water will easily transfer that heat into the water itself, leave the deserve to ice cold much much more quickly 보다 if girlfriend left the soda in her refrigerator.

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

This is partly due to water’s very own chemical properties and the truth that water is a much denser repertoire of molecules than ambient air. Every one of that water deserve to run over the surface ar of your deserve to of soda, touching much more of the have the right to than waiting does in less time.

The more surface area got to by the ice cream water, the quicker the cooling process takes place. Because water maintain heat very well, there won’t be lot of a feedback loop, therefore your deserve to will continue to be cold rather than sucking up heat that the water take away on native the environment.

Overall, making use of an ice bath to cool under a can of soda need to only take it a few minutes together opposed to the hours compelled by a modern-day refrigerator, and also all without the threat of one explosive mess that comes v using a freezer.
