correct statement about contaminant transport?
- Advection refers to contaminant transport with flowing water.
- Both diffusion and mechanical disperion are associated with concentration gradient.
- Sorption refers to the process of contaminants sorbed to the solid phase.
- Sorption process follows a linear sorption isotherm in the range of high concentration of contaminant.

Expert Solution
1) True - Advection is a process of transportation of contaminants which is caused by the flow of groundwater in the subsurface .
2) True- Diffusion is a process of movement of partcles from a region of higher concentration to a region of lower concentration.
Mechanical Dispersion is a process of dilution of the contaminant water on mixing with the groundwater.
3)True-A process of one substance being attached to another sunstance is called Sorption , which is a chemical and a physical process. In contaminant transport, the contaminants get sorbed to solid phase sorbents like rock , soil etc .
4)False - In the range of high concentration of the contaminant , the process of sorption follows a nonlinear sorption isotherm .

Which statement A-D about chemical bonds is not correct?
Which statement A-D about chemical bonds is not correct? a. The attraction of the negatively charged electrons to the positively charged nuclei causes the electrostatic potential energy to decrease as two atoms come together. b. The repulsion of the negatively charged electrons with each other and the positively charged nuclei with each other causes the electrostatic potential energy to increase when the two atoms are very close together. c. As two atoms come together, the electrostatic potential energy goes through a minimum. The...

Which is CORRECT about information asymmetry and adverse
selection
Information asymmetry refers to the situation when buyers have
more information on the product than the sellers.
Information asymmetry is the result of adverse selection.
In a used car market, if sellers with good cars are unwilling
to sell at a large discount, then only bad cars will get sold. This
suboptimal outcome is so-called “adverse selection”.
Due to information asymmetry, market investors interpret firm’s
SEO announcement positively because they believe...

The kidneys handle Na+ in different places of the nephron. Which
statement is correct?
Water is filtered out of glomerular capillaries by bulk
flow.
Water is actively reabsorbed from the proximal tubule, and Na+
follows down its diffusion gradient.
The permeability of the ascending limb of the loop of Henle is
modified by vasopressin.
Vasopressin inserts pumps in the collecting duct membrane that
move water against its concentration gradient.
