Answer 1

$\huge{\boxed{\mathcal{Answer}}}$

•A plastic cube when released in water will come to the surface of water. Or we can say that it begins to float on water surface and doesn't sink.

•It is important to note that whenever an object has lighter density than water, the object floats.

•And whenever the object is heavier than the density of water it sinks.

•Plastics are made of hydrocarbons which is lighter than the density of water. So plastic cube floats on water.

•Also, it has been found that plastic has high rate of buoyancy force i.e., an upward force due to which the plastic cube floats on the surface of water.
