What is the difference between rate of percolation and the amount of water retained? Ans:- Rate of percolation id the amount of water percolated, per unit time through soil. Whereas the amount of water retained is the amount of water absorbed by soil.

Particle Size The smaller a soil's particles are, the greater the soil's surface area is, and so the more water the soil retains. Clay soil has small, fine particles, which is why it retains the most amount of water.

Generally, the amount of dissolved solids in water determines the electrical conductivity. Electrical conductivity (EC) actually measures the ionic process of a solution that enables it to transmit current. According to WHO standards, EC value should not exceeded 400 μS/cm.

Our model shows that as grain size increases, the weathering rate initially decreases; however, beyond a critical size no significant decrease in the rate is observed. This transition occurs when the density of reactive boundaries is less than ∼ 20 % of the entire domain.

More sorted particles have a higher porosity. Smaller particles have a low permeability. This is because there is less space between particles, which causes a lower porosity, which makes water travel slower through the ground. Smaller particles have a higher capillarity.

Permeable surfaces (also known as porous or pervious surfaces) allow water to percolate into the soil to filter out pollutants and recharge the water table. Impermeable/impervious surfaces are solid surfaces that don't allow water to penetrate, forcing it to run off.

Drying and Evaporation. Difference between drying and evaporation: ... In most cases drying involves the removal of water at temperatures below its boiling point, whereas, Evaporation means the removal of water by boiling a solution.

Answer: Specific Conductivity decreases with a decrease in concentration. Since the number of ions per unit volume that carry current in a solution decrease on dilution. Hence, concentration and conductivity are directly proportional to each other.

When people discuss osmosis in biology, it always refers to the movement of water. ... One big difference between osmosis and diffusion is that both solvent and solute particles are free to move in diffusion, but when we talk about osmosis, only the solvent molecules (water molecules) cross the membrane.

This highlights a noticeable difference between osmosis and facilitated diffusion. Osmosis involves movement of water molecules across a semi permeable membrane. ... A major difference can be noted that osmosis requires water molecules but facilitated diffusion does not require any water molecules.

Explanation: Simple diffusion is the movement of molecules from an area of higher concentration to lower concentration. ... Osmosis is the movement of water from an area of less concentration of dissolved particles to an area of high concentration, thus equalizing the concentrations on each side.

Answer Expert Verified Correct answer: Diffusion is the movement of particles from a high to low concentration, while osmosis is the movement of water from a high particle concentration to a low particle concentration.

Diffusion sees molecules in an area of high concentration move to areas with a lower concentration, while osmosis refers to the process by which water, or other solvents, moves through a semipermeable membrane, leaving other bits of matter in its wake.

The difference depends on the supply of heat: Evaporation can take place at any temperature while boiling happens only at the boiling point. Another difference is, evaporation takes place only at the surface of the liquid while the boiling is a bulk process where vaporization takes place throughout the liquid.

This effectively lowers the concentration of water. Water Potential measures the concentration of free water molecules. ... The more free water molecules, the higher the Water Potential. Water diffuses by Osmosis from a region of high Water Potential to a region of low Water Potential through the Water Potential Gradient.

Increase the rate of diffusion. Describe the difference between the rate of diffusion seen for sodium and urea. Urea diffused slowly because it is larger than sodium.
