Question

5. Density helps to understand (a) the motion of materials (c) floating or sinking of an object in the water (b) the motion of gases in atmosphere (d) none of the above​

Answer 1

Explanation:

Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.
