It depends on the density of a material. The density can be calculated using: density = mass/volume.
This means that a very heavy object like a tanker can float on water because it has a large volume which makes its density less than that of water.
No, some sink.
it will float
It is to do with to volume and mass.
Because some objects are a lot denser than water so the sink and others are less denser so they float
A submarine
objects with higher density than water sink, ones with a lower density float
Because of the objects density.
because some objects are much denser(heavier) than water so they sink
yes
Because of the comparative density. If the objects density is greater than water it will sink, if less then it will float.
It will float.
Because air has weight, mass, and density objects will either sink or float in it. Some balloons will float for example.
