A lot of people like to drink a cold soda on a hot summer day, but they forget to put it in the fridge. You could put it in a cooler, but is there a better and faster way. First, you need to know that fizz affects the temperature of a soda. “The “fizz” in a soda is really the action or sensation you observe as dissolved carbon dioxide is released by the soda. The main variables that affect how fast the soda gives up the carbon dioxide are temperature, pressure and mechanical agitation.”(Marz, Copyright date: March 13) Carbon dioxide is what soda fizz is made from, and it creates pressure inside the can. When you open a can the pressure is released and if the soda is colder than it allows more CO2 to be dissolved. Without the CO2 in your soda, your soda would be flat and it wouldn’t be very refreshing to drink. It is always better to drink a soda when it is cold for one very important reason. That reason is that when the soda is cold, the C02 molecules have less energy to go into the air. That is why cold soda is fizzier than soda that has been sitting out in the heat for a long time. If the soda is warmer than more CO2 will be released into the air. If you decide to warm the soda, that will cause the gas to be released into the air. Temperature and agitation are in charge of how fast or slow the C02 comes out of the bottle and goes into the air.
Agitation is the action of something stirring, and that is mostly a liquid. If you keep the bottle or can of soda very still and very cold, then you will slow down the loss of the fizz. Ice is one of the most common factors for cooling down a soda. When ice is placed into a glass of soda, it absorbs energy because heat always moves to colder areas to equalize temperatures. Ice makes the water molecules lose a lot of energy, and because of that the molecules slow down and then they begin to cool down the soda. Since ice floats, the ice cools the soda that is on the top of the glass first. Once the top of the soda cools, its density starts to increase, causing it to sink all the way to the bottom of the glass of soda. After that, the lower layer of the soda flows up to the top because it is less dense and it has more buoyancy.
Buoyancy is a force that uses the upward direction against the force of gravity, and because of that it makes an object or liquid feel lighter when it is placed into a liquid. You might be thinking that there is only one molecule in a can of soda, but that is not true. There is water molecules in soda, and they take up 95% of the whole soda. Water molecules are made out of one oxygen atom and two hydrogen atoms. One of the two things that make the soda taste good is the sweetener inside of the soda. The sweetener in the soda is glucose and fructose. If you mix glucose and fructose together, it makes a different kind of sweetener called sucrose. There is 39 grams of sugar inside of a bottle of coke. That is 78% out of the whole can. If you put a can of soda into a refrigerator, there is a likely chance that the can will explode and the soda will spill everywhere. That is because Soda cans are designed to hold a specific volume of liquid. When placed in the freezer, the water in the soda expands inside the can, and the volume becomes greater than what the can was designed to hold. This pressure causes the can to become strained and to eventually POP when left in the freezer for too long “(Mcdevitt, Copyright Date: October 5, 2016)
Carbon dioxide always continues to escape, and if you have a bottle of soda recapping it increases the pressure and slows down the speed of the carbon dioxide, so it won’t all escape into the air. Warm sodas do seem to have more fizz, don’t they? Actually, bottled soda doesn’t gain any carbonation when it’s warm.”( University Of California, Copyright Date: February 26, 2005). To make a soda bubbly, the factory will use a high-pressure tank to pump in lots and lots of carbon dioxide (the same stuff that we breathe). Then, they seal the can or bottle so that none of the carbon dioxide escapes. ( University of California, Copyright Date: November 14, 2014) A soda has a specific volume that it can hold. If you add heat to it, you are increasing the volume.That is called the Charles Law. The Charles Law is the ratio of temperature and volume of a gas should be the same. If you add heat, the volume will increase.
