The cans of regular pop are more ... WitrynaIf an object or substance is less dense (having less weight) than other components in a mixture, it will float. When an object floats, it displaces a weight of fluid equal to its own weight. Science ABC uses a bucket of water and some rocks to explain this concept: When tossing rocks into a bucket of water, the rocks will sink. This is because ... WitrynaAn example of a very dense item is a penny. A cork is less dense. A penny, paperclip, or button sank because the materials they are made of (metal for a paperclip and penny, plastic for a button) had more density than water. (Their molecules are closer together than water molecules are.) A cork, piece of wood, or Styrofoam floated because … graph y 4x - 5
