[quote=alemracloveyajr]CHEMISTRY: You know very well that when a liquid is cooled, its molecules move slower and thus it solidifies. Most solids have higher density than water so they tend to sink in water. One hot day, you put two ice cubes on your soda and you noticed that the cubes floated. Why didn’t the solid cubes sink?[/quote] don't generalized that all solids are have a higher densities.. ice cube is water but in a form of solid.. right.. those ice cubes are less denser than water.. for example, when you put an ice cubes into your water it will float, right.. so, in your case.. definitely, that your two ice cubes will be float in your soda because those two ice cubes is less denser than soda.. hope you get what i mean..
