100 Mind-Blowing Densities Facts
Lemons float, but limes sink. This is because of their different densities, often causing unpeeled limes to sink if submerged in a liquid.
Sponges hold more cold water rather than hot. This is mainly due to the effect of heat on water on a molecular level. Cold and hot water will have two different densities, and as such their molecules will react differently when in contact with an object. The water molecules or colder water tend to move slower and do not go in opposite directions from each other.
