The answer is; liquid phase
The characteristics described in the question are those of a liquid. The forces between liquid particles are weaker than the forces between solid particles because the particles are further apart. The particles are not held in a fixed position in the structure hence it can flow and take the shape of the container in which it is in.
PH = -log [H+]
pH = -log (1.0x10^-4) = -(-4) = 4 or A
1) Troposphere is the nearest layer to the earth.
2) Range from 5 to 11 miles in thickness.
3) Contains almost all of the atmospheric water vapor.
