Why are objects floating or sinking in these pictures?

  1. The object is floating in the picture above the comment box, the object is floating because it has salt in it. In the fresh water it is sinking because there is no salt inside.Salt hold the weights of an object.

  2. The ping pong ball floats because it is lighter than the liquids in the jar. The bolt is heavier so it sinks.

  3. Some objects are lighter than the liquids so they float and objects sink because they weigh more than the liquids.

  5. The ping pong ball floats on the lamp oil because it has the least amount of density.

  6. the ping pong ball floats in the salt water because the salt water has more mass so its harder to sink.

  7. The egg in the salt water floats because the salt water has greater density than the fresh water, so it pushes things to the surface.
    The egg in the fresh water goes to the bottom because it has greater mass than fresh water. Fresh water has less density than salt water.

  8. It seems like the ping-pong ball has the least density because it's floating on top of all the others and the bolt has the most density because it sunk to the bottom of the container.
