Air's density is less than that of water. Water's density is almost 800 times greater than air.
The water density is 1 g/cm3 and the air density is 0,0012 g/cm3 .
When you compare density, you compare the weight of the materials with equal volume. So you cannot compare the density only by weight. The right answer for this is, Platinum has the density of 19.8 gr/cubic centimeters at room temperature versus Golds 19.3 gr/cm3.
Most dense: Water Medium: Ice Least dense: Steam
Pine cones float because they are less dense than the water, so they float. When you put them in right-side-up, the air gets trapped under the water. This causes the air bubbles to push up which makes the pine cone float.
I do not know
If it sinks in water then it has a higher density than water. If it floats on water surface then its density is less than water.
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.

The water would have the same density anywhere it is.
Ice is less dense than liquid water.
Ice is less dense than liquid water.
A fresh chicken egg will sink, an old egg will float. The egg has an air pocket in the blunt end that grows as the egg dries out.
It is greater than water. It sinks.
Cold air is heavier than warm air.
The density of water is 1000 kg m-3 The density of the moon is 3346.4 kg m-3 So the density of the moon is 3.3464 times that of water.
Average density of the object compare to density of water. If denser than water, it will sink.
No change. Crushing just pushes out air.
Yes. That's what specific gravity is.
