Question

Could Saturn float on water and why?
A. Yes, because its density is less than the density of water.
B. No, because its density is more than the density of water.
C. Yes, because it is a celestial body.
D. No, because it has rings.

Answer 1

Hint: An object sinks or floats based on the density of an object. Compare the density of Saturn with the density of the water and conclude the result accordingly.

Complete step by step answer:
Saturn, a sixth planet of our solar system that is a planet Saturn holds sixth position from the sun in our solar system. It is a massive planet. Saturn is the second largest planet of our solar system; Jupiter holds the first position in terms of the size of the planet.
What is the requirement of any object or any planet to float in water? The main thing is its density. If the density of any object or any planet is less than the density of water so that object or that planet will float in other otherwise not. In simple words if the planet or the object is lighter it will be in water otherwise it will not float.
Major part of Saturn is made up of gases and this is the reason the density of Saturn is lowest among the entire planet of our solar system and even lower than the density of the water. No other planet in our solar system can float on water due to their heavier density. Due to its lower density than the water Saturn can float in water.
So, the correct option is a.

Note: Another approach is to remember Saturn has lower mass than the mass of water for the same exact volume. Then use the formula, mass is equal to density and volume. And find the required density.
