©1998, University of Wisconsin, Board of Regents. The cans are the same size and they contain the same amount of liquid according to the label. If the crown had been made with less dense materials than pure gold including silver , it would displace more water than the gold bar. It felt heavier because it has more mass or more stuff in it. I personally just take normal soda only once in a while instead of … everyday.
Note the Diet Coke breaking the surface on the left. Because less weight of sweetener is very likely dissolved in diet coke, compared to sugar in regular coke, then the weight of diet coke is less than regular cok … e for the same unit volume. I tested room temperature cans in hot, room temperature, and cold water, and every single time, the Pepsi sank and the Diet Pepsi floated. Were all the cans you tried at room temperature before you put them in the water? Sugar and artificial sweeteners are both more dense than water. The answer, is the type of sweetener used in each pop.
But their density differs due to what is dissolved in the soda. The Diet Coke can floated to the top, while the regular Coke sat on the bottom. The King had a doubt that the jeweler stole some of the gold he had given to him. And how much compared to the total amount of the product in the bottle?. This post is just for reference for anyone looking through the forums. Does anyone have code rewards codes. Regular and Diet Coke Cans in Water Regular and Diet Coke Cans in Water Due to the difference in density, the can with the sugar in it sinks while the diet can floats.
The dependent variable is whether the can will float or sink in water. Another fun fact: In any event, initially, this floating problem seems like something that breaks physics because both cans are the exact same size and contain exactly the same amount of liquid. Since they both use a standard can, I decided to weight a few cans Coke and Diet Coke that I have around the house. Does it sink or float? Regular Coke contains a significant amount of sugar, which makes it denser than water, so it sinks. Objects with a lesser density than the substance it is submerged in will float.
Surprisingly enough, this one has some truth to it. This 3% difference in density as compared to that of water is enough to allow the can to float as in the photograph above. The only difference between diet soda and regu … lar soda is the sweetener. One more fun fact is that the man who invented Coca-Cola was actually seeking a cure for the morphine addiction which he acquired during the Civil War, and he marketed Coca-Cola in that way. However, if you put a can of Diet Coke into the same pool, it would float. Eventually, Archimedes hatched a cunning plan to submerse the crown and measure the amount of water it displaced and compare that to the amount of water displaced by an equal mass of pure gold.
The can of Diet Coke contains , resulting in a density nearly equivalent to that of water indeed, slightly less , so it floats. Cold water is denser than hot water, thus it is a tiny amount easier to float in cold water than in warm. A student had asked if pouring the regular Coke into the water might raise the can of Diet Coke above where it had been floating. Due to aluminum's chemical nature, it degrades unbelievably slowly unless it comes into contact with specific disruptive chemicals. As aluminum is remarkable for its ability to resist to corrosion or rusting due to the phenomenon of passivation and its low density, the rusting process is extremely long. By adding salt to the tank, you can increase the density of the water which is now salt water.
For another look at how dissolved sugar affects the density of a solution, see the experiment. Place a can of regular soda into the water. Because it takes hardly any aspartame or the equivalent to make a can of Coke taste sweet, the addition of the sweetener does next to nothing to change the density of the liquid in the can. Adding 13 g for the can brings this to 384 g, for an overall density of 1. The soda cans are sold as containing 12 ounces, or 355 ml, of liquid. So diet soda doesn't need as much of a sweetener to make it sweet. Then tying them together open end down, figuring that no more than half the can will fill with water on average.
It's pretty heavy when you think about it. A person who wants to be on a diet avoids sodas all together. Hello, I am helping my daughter with a science experiment. To be safe, the beaker contains about 275 grams of salt, which is more than enough to raise the heaviest Coke can listed above. This makes the density of the Coke liquid greater than that of pure water, so the regular Coke sinks. And, in fact, a 12 ounce can of Coke has more mass because of the it contains, compared to the in a can of Diet Coke. We work through my and explore the investigation together.
Results My result is that both my cans floated just as yours did. Fun fact: If you put a can of Coca-Cola into a pool of water, it would sink. For the 15-liter tank, this would be approximately 225 g of salt. However, diet soda contains an artificial sweetener known as aspartame and it is a foreign chemical that you are injesting. Rocks have a high density and sink, the foam in life jackets has a low density and it floats. Density the mass per unit of volume determines how much liquid is displaced. Cans of regular soda tend to be more dense than water, so they sink.
