Does Coke Carbonate in a Submarine?

The answer is a resounding No. But before diving into the details, let’s explore the fascinating topic of carbonation in fizzy drinks and the special conditions found in submarines.

What is Carbonation?

Carbonation is the process of dissolving carbon dioxide gas in a liquid, such as water or a soft drink like Coca-Cola. This results in the formation of a weak acid, carbonic acid (H2CO3), which gives carbonated beverages their characteristic fizzy or bubbly quality.

How Does Coca-Cola Carbonate?

Back on land, Coca-Cola carbonates its drinks by injecting carbon dioxide gas under pressure into the beverage while it’s being bottled or canned. This process occurs at the manufacturing plant or at the bottling lines. The carbon dioxide molecules (CO2) mix with the water and ingredients in the drink, resulting in the formation of carbonic acid and the telltale fizz.

Submarine Environment: Not Ideal for Carbonation

Now, let’s travel to the underwater world where submarines operate. Submarines are designed to function in extreme environments, often at depths of over 1,000 feet (305 meters), with crushing pressures, and near-freezing temperatures. The submarine’s hull is pressurized to maintain a relatively normal atmosphere inside, allowing the crew to breathe comfortably.

Why Can’t Coke Carbonate in a Submarine?

1. Lack of Carbon Dioxide: In a submarine, the high pressure and low temperature can cause the carbon dioxide in the air to condense and form ice, effectively removing it from the equation. This means there isn’t enough CO2 present to carbonate the drink.
2. Inconsistent Pressure: The pressure within a submarine is not uniform, and the pressure vessel used to store the Coke would need to be modified to accommodate the varying conditions. This would add significant complexity and cost to the system.
3. Temperature Issues: The average temperature inside a submarine can range from 32°F (0°C) to 50°F (10°C), which is much colder than the average refrigerator temperature. This low temperature would slow down or even halt the carbonation process.
4. Limited Storage Space: Submarines have limited storage space, and the requirements for carbonation equipment and CO2 storage would likely exceed available space.

Additional Challenges

• Electricity Generation: Submarines rely on onboard diesel generators or nuclear reactors to generate electricity. This presents a challenge for powering the carbonation equipment, as it would require additional capacity and energy consumption.
• Water Quality: Submarines use seawater desalination systems to supply drinking water. The treated water may not be suitable for carbonation, as impurities or minerals could react with the CO2.
• Crew’s Health: The submarine crew’s health and well-being are paramount. Carbon dioxide can be a health risk in enclosed spaces, making it essential to prioritize alternative beverage options.

The Verdict: No Fizzy Drinks in Submarines

In conclusion, the conditions inside a submarine make it impossible to carbonated Coca-Cola or any other fizzy drink using the traditional method. The answer is a straightforward No. However, this doesn’t mean the submarine crew goes without their favorite beverages. Submarines often carry a variety of non-carbonated drinks, such as juice, tea, and coffee, to keep the crew satisfied and hydrated during their mission.

Table: Beverage Options on Submarines

As we’ve seen, Coca-Cola carbonates in a controlled environment, not in a submarine. The unique conditions found underwater make it impossible to create the fizz we associate with carbonated drinks. For the submarine crew, the focus is on staying safe, healthy, and caffeinated with alternative beverage options.
