Why does ice become less dense than water?

1 answer:

8 0

Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.

Answer:

Diversity of the community = 2.097

Explanation:

Given:

Number of pitch pines = 134

Number of douglas firs = 24

Number of red pines = 53

Find:

Diversity of the community

Computation:

Simpson's diversity index = N(N-1)/Σn(n-1)

Particular n n(n-1)

Pitch pine 134 17822

Douglas firs 24 552

Red pine 53 2756

Total N=211 21130

So,

D= [211(211-1)] / 21130

D = 2.097

Diversity of the community = 2.097
