Question

Saturn has specific gravity :

• A. Less than that of water
• B. Equal to that of water
• C. More than that of water
• D. None

Answer 1

The correct option is A Less than that of water

Specific Gravity of any object is defined as the ratio of its density to the density of water.

$\text{Specific density}=\frac{\text{density of the object(Saturn)}}{\text{density of water}}$

Where,

$\text{density}=\frac{\text{mass}}{\text{volume}}$

Saturn is even lighter than water. This means its density is less than that of water. Hence its specific gravity is less than that of water.

The fascinating thing is that if Saturn falls on a large body of water, even larger than Saturn, then it will float on water.
