Question

Why do we compare density of a substance with water

Answer 1

Answer:

Using Water as a Density Comparison

When an object is placed in water, the object's relative density determines whether it floats or sinks. If the object has a lower density than water, it will float to the top of the water. An object with a higher density will sink.

Answer 2

When an object is placed in water, the object’s relative density determines whether it floats or sinks. If the object has a lower density than water, it will float to the top of the water. An object with a higher density will sink.
