Answer:
The study of movement, distribution and quality of water.
Explanation:
They measure the properties of bodied of water, such as the volume of and stream flow.
80 liters of water
this is a mixture problem.
75% x 20 = 1500 (acid solution)
0 x X = 0 (water)
15 x 20+x = 300 + 15x
looking at column 3, we get 1500+0 = 300+15x
using properties, x=80
