SUMMARY

The discussion centers on comparing the density of a rhino to that of a rock, specifically a glacial deposit. It is established that flesh, primarily composed of water, has a density of approximately 1000 kg/m³, while rocks typically have a density of at least 1.5 to 2 times that of water. Consequently, a rock of the same size as a rhino will be significantly denser and heavier due to the air content in the rhino's body, which reduces its overall density. Therefore, the rock is definitively denser than the rhino.

PREREQUISITES
  • Understanding of basic density concepts
  • Knowledge of material properties, specifically the density of water (1000 kg/m³)
  • Familiarity with glacial deposits and their characteristics
  • Basic biology regarding the composition of living organisms
NEXT STEPS
  • Research the density of various rock types, particularly glacial deposits
  • Study the composition of living organisms and how it affects density
  • Explore the principles of buoyancy and density in biological contexts
  • Investigate the physical properties of water and its role in biological structures
USEFUL FOR

This discussion is beneficial for students of biology, geology enthusiasts, and anyone interested in understanding the physical properties of living organisms compared to geological materials.

What would have a higher degree of density?

A rhino the Size of this rock or the rock itself?

I assume you have a point in posting this picture of what is obviously a glacial deposit.
 
I just wanted know if the rock( which is essentially a glacial deposit)is more dense than a rhino that would be the same size.
Is flesh generally less dense than stone?

I liked this question.
Lets assume the flesh is made up of Water, (ρ=1000kg/m) cool.
Secondly, the rock, assume any rock or in general, it would have twice the density that of water or let's say, 1.5 times the density of water.
So rock will be heavy.
Secondly, Rhino will have air inside it, so the density would decrease considerably.
My opinion is that, the rock will still be Heavier compared to Rhino. (I feel even his tusks and skin won't affect much).
 
Living objects are mainly made out of water, so their density is close to 1000kg/m^3.
I don't know the type of this rock, but a usual density would be at least twice this value.
