Which best describes the difference between osmosis and diffusion? osmosis is the movement of particles from a high to a low particle concentration, while diffusion is the movement of water from a high to a low water concentration. diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration. diffusion is the movement of particles from a low to a high particle concentration, while osmosis is the movement of water from a low to a high water concentration. osmosis is the movement of particles from a low to a high particle concentration, while diffusion is the movement of water from a low to a high water concentration.

Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.

Explanation:

Osmosis refers to the movement of water molecules through a selectively permeable membrane. The movement always occurs from the region of higher concentration of water to that of lower concentration. Osmosis does not include the movement of solutes.

Diffusion is the movement of substances from higher to lower concentration region. Diffusion is not restricted to movement of water only.

explanation:

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
