Why does the Diet Coke float in water while the Regular coke sinks?

Answer 1

The Diet Coke will float because it is less dense than water and the regular coke will sink because it is more dense than water.

In regular coke, more sugar is used as a sweetener also makes it more dense than water and the more dense the substance, it is the more likely to sink.

Aspartame and Saccharin are artificial sweeteners found in Diet Coke. They are at least 200 times sweeter than table sugar. Therefore, a smaller amount of sweetener is used to sweeten the diet coke.

• Density is the amount of mass in a volume (mass/volume).
• Any substance that is less dense than water is likely to float
• Any substance that is more dense than water is likely to sink.

Answer 2

Artificial sweeteners are more concentrated than sugar. You need less weight of the sweetener compared to sugar, to make the product sweet. 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 coke for the same unit volume. This is the property called density, weight per unit volume. Water happens to have a density of 62 pounds per cubic foot. It's pretty heavy when you think about it. Because coke is mostly water and anything added to it would make it heavier than water, then both coke and diet coke would both be heavier than water and would make the can want to sink. You must however look at everything together.

Answer 3

It is less dense than regular soda because of the lack of SUGAR.
