Question

What does it mean, if the specific gravity of an object is greater than one?​

Answer 1

Specific gravity can be used to determine if an object will sink or float on water. If an object or liquid has a specific gravity greater than one, it will sink. If the specific gravity of an object or a liquid is less than one, it will float.

Hope this helps, have a great day/night, and stay safe!

Answer 2

When the specific gravity ratio for a given material is greater than 1, that means the material will sink in the reference substance. This is related to the concept of buoyancy. The iceberg floats in the ocean (as in the picture) because its specific gravity in reference to the water is less than 1.
