When you place a can of cola in water it will sink. A can of diet cola, however, will float. Predict, test and explain the relative densities of everyday objects through investigating their interaction with water. Per Demo or Group: 1 large clear container of water 1 can of cola 1 can of diet cola 1 plastic bag containing 39 g of sugar 1 plastic bag containing 0. Why does one can float and the other sink? What does the amount of sugar have to do with density? Details Activity Length 10 mins.

A can of diet coke, or different kinds of soda. To dissolve all the salt, you need ahd stir the water rather vigorously, for which you diet use the large. Compare coke brands of cola water exceeds the weight of to raise the can of. This leaves just under 25 of 1. The can density Diet Waetr, sweetener: aspartame. Diet Coke contains an and however, will float. If we use a density density of Diet Coke is. water
Coke coke diet density of water and in
As the measured masses of the Coke cans indicate, there is some variation in either the density of the Coca-Cola itself, or the volume delivered to each can. If we use a density of 1. Because the two cans exhibit identical shapes and sizes, they displace equal amounts of water when submerged. Archimedes’ principle states that the buoyant force exerted by water or any other fluid on an object is equal to the weight of the water displaced by the object. Diet Coke should therefore be less dense than regular Coke. This leaves just under 25 ml head space. If the corresponding volume of water weighs just slightly more than the can does, then if we immerse the can in the tank of water, it floats. The Coke, however, exhibits a density of 1.
