It's a color chart.
Ice floats because it is less dense than water. When water freezes, it creates a crystal lattice that occupies more volume than the water did. Because it is less dense, ice is displaced by water (and floats on top).

Pressure is the correct answer in this situation
Answer:
0.371
Explanation:
number of moles = mass / Ar
= 23.8g / 32.1 + (16.0 × 2)
= 0.37129485179 = 0.371 (3 s.f).
hope it helps :)
Answer:
The entropy of the products of a reaction is always greater than the entropy of the starting materials
Explanation:
The second Law of Thermodynamics says that entropy always increases
A + B ----> AB
A and B that were completely arranged in their structures had to be completely messy to form compound AB
When an isolated system reaches a maximum entropy configuration, it can no longer undergo changes: it has reached equilibrium.
