Explanation:
For a flower to appear blue, "it needs to be able to produce a molecule that can absorb very small amounts of energy," in order to absorb the red part of the spectrum, Kupferschmidt said.
10kg of gold is more denser than 100 kg of ice
.
<u>Explanation:
</u>
Density of a substance purely depends upon the mass and its volume occupied in the system.
In the above statement it is a comparison made between 100kg of ice vs 10kg of gold.
Density of ice in general is 0.920
and Density of gold in general is 19.3
So if we calculate for 100kg of ice,
Density=100×0.920=92 
Similarly we can calculate for 10kg of gold we get
Density=10×19.13=191.3
If we compare the above two values we can say that
Density of 10kg gold has greater value than the Density of 100kg water.
