Question

Why do objects sink or float in water​

Answer 1

The density of an object determines whether it will sink or float in water. If an object's density is greater than water, it will sink. If an object's density is less than water, it will float.

Answer 2

Because their density is either less or more than water's density, which is 997 kg/m³.

Objects sink if their density is more than 997 kg/m³.

Objects float if their density is less than 997 kg/m³.
